Hens
2The Four Factors for JudgingLaying Hensin order
of importance
- Pigment Loss
- Handling Quality
- Body Capacity
- Molt
3- Look at the class as a whole.
4What To Look For As A Group
- 1. Look for birds that are
- - Alert and vigorous layers
- - Dull appearing non-producer
- 2. Observe their heads
5- Here you see a vigorous hen, with a large red
comb and wattles, and a bright alert eye. This
hen shows she is in good production.
6- Here is a bird that shows a lack of vigor by the
way she holds her head. The comb and wattles are
shrunken and white, her eye is dull. These
conditions indicate she is not in production.
7- After making distant observations, you are now
ready to handle the birds.
8- After removing the hen from the coop we will
learn how to examine her for pigment loss,
handling quality, body capacity, and molt - Remember she will be upset as you try to catch
her.
9Removing hen from coop
- Reach in with one hand, place it on her back and
firmly, but gently, hold her to the coop floor. - Gently grasp one wing and turn her head toward
the door.
10- 3. Quickly thrust the other hand under the hen so
that the keel sits in your palm, her head toward
the door. Hold her in both hands to make the
bird comfortable. - 4. Lift her off the floor.
11- Supporting the hens weight in your palm, and
giving balance with the other, remove the bird
from the cage head first.
12Holding the bird for examination
- To examine the bird, hold her head down with her
back against your stomach. Hold the legs just
above the hocks with the thumb around one thigh,
the first finger between the hocks and the second
finger around the other thigh. Your other hand
is free to gently examine the bird.
13Pigment Loss
- Pigment loss is the most important factor to use
in deciding which hen is the best layer. The
diagram on the next slide gives the order of
pigment loss, you will need to know this very
well (hint, hint). - The more pigment loss the more eggs the hen has
laid.

15The Vent
- Move the feathers away from the vent so you can
see its shape and color.
16Eye Ring
- Hold the bird up in your palm and grasp the head
gently with your free hand. - With the thumb, pull down on the face skin so you
can see under the eye. The eye ring is the edge
of the eye lid. This allows you to look at the
pigment in the eye ring.
17Ear Lobe Beak
Move the thumb down and stretch the ear lob. A
creamy color indicates the presence of
undesirable yellow pigment
- The first finger of your free hand makes a good
background for contrast in looking for pigment in
the beak. Look at the base of the beak where my
thumb is pointing and move towards the tip. It
is best to look along the edges of the beak where
they meet.
18- With the bird against your stomach, grasp the
foot gently to expose the cracks in the skin
between the toe joints. When the feet are dirty,
this lets you see the pigment on the bottom of
the foot.
19The Shanks
- Hold the hen with her back against your stomach,
turn the bird sideways and gently twist the feet
upward so you can see the front of the shanks.
Use your free hand to cover the tops of the feet
to hide any pigment that would distract your
perception of yellow color in the shank. - Pigment loss from the front of the shank begins
at the top and fades downward toward the top of
the foot.
20Back of Shank
- Return the hen to a normal holding position and
cover the bottom of the feet so you can better
see pigment loss from the back of the shanks.
Loss should begin at the bottom of the shank and
move up to the hock.
21Toe Tops
- Again turn the hen sideways, and look at the top
of the toes. In some high producers, pigment may
remain in the top of the foot.
This completes the examination of the hen for
pigment loss. Remember, as color is lost from
more of these skin areas, the better the layer.
22The next factor in importance is handling
quality. The pubic bones should be flexible and
thin with sharp edges. The abdominal skin must
be velvety thin, while the shank scale are rough
and there is a groove down the side of the shank.
These conditions indicate the hen is not putting
on body fat. A fat hen is a poor layer.
23Locating Pubic Bones
My fingers are depressing the abdomen just below
the vent, showing the two pubic bones.
24- Now we look for the rear tip of the keel bone.
You will need to know this later to measure body
depth. It is located to the right of my finger.
25- This picture shows how to hold the ends of the
pubic bones to check their flexibility by
pressing outward with a finger while pressing in
with the thumb. Be careful not to break the
bone. - By moving the fingers along the bone edge, you
can feel its sharpness or absence of fat.
26- Just below the pubic bone, very gently roll the
skin between the thumb and finger. Thin velvety
skin is a desirable indication of a lack of fat.
27Body Capacity
- Body capacity is third in importance, and
indicates an ability to lay large eggs. It is
measured by body width and depth.
28Body Width
- Here we see a body width of two fingers between
the pubic bones.
29Body Depth
- Body depth is measured between the pubic bones
and the tip of the keel. This hen has a body
depth of three fingers. - Put width and depth together for a body capacity
of two by three fingers
30Molt
- Molt is the last factor in importance for
judging. - A hen molts when she stops production. Therefore
molt can be used to determine how long her laying
year was. - Some birds molt faster than others, multiple
feathers at once.
31- Hold the bird level with her head toward you.
Grasp the front of the wing and open it like a
fan. Locate the axil feather, the short one
raised in the middle of the wing.
32- Now observe the primary flight feathers outside
the axil feather. They are replaced from the
inside out. - This hen has old feathers, worn on the ends,
indicating she has not molted, and has been in
production a long time.
33RECAP
- The judging factors in order of importance.
- Pigment loss
- Handling quality
- Body capacity
- Molt
- The order of pigment loss.
- Vent
- Eye ring
- Ear lobe
- Beak
- Bottom of foot
- Front of shank
- Back of shank
- Hock and top of the toes
34Vent of a GOOD layer
- This hen has lost all the pigment from the
outer skin in the vent. While the vent itself is
moist and loose in appearance.
35Vent of a POOR layer
- The vent of a poor layer will be tight, dry
and show yellow color in the outer skin area.
This slide shows a typical vent of a poor
producer.
36Eye ring of a GOOD layer
- Here you see the white chalky appearance of
the eye ring and lower lid of a good layer.
37Eye ring of a POOR layer
- Notice the yellow color in the edge of the eye
ring and lower lid of this poor producer.
38Ear lobe of a GOOD layer
- Leghorns like these have white ear lobes.
This good layers ear lobe is chalky white in
appearance.
39Ear lobe of a POOR layer
- Note the smooth waxy appearance of this ear
lobe. Sometimes the color is so deep the ear
lobe will be creamy yellow. This hen is such a
poor layer that you can also see a yellowish cast
to the red face skin and wattles.
40Beak of a GOOD layer
- This good layer has lost all pigment from the
beak which appears translucent compared to my
finger. - Remember, the farther down the order of
pigment loss color has bleached, the better the
layer.
41Beak of a POOR layer
- Note the yellow pigment in the corner of the
beak just above my thumb. Follow the edge of the
upper-beak, you can see the pigment carries
forward to the tip of this poor producers beak.
42Bottom of the foot of a GOOD layer
- Notice the pink tone of the web and bottom of
the toes indicating a lack of yellow color. She
has laid more eggs than a hen that has lost
pigment only through the tip of the beak.
43Bottom of the foot of a POOR layer
- In the case of this poor layer, observe the
yellow cast to the skin of the web and toes.
This means she has laid fewer eggs than the hen
who is bleached through this area.
44Front of shank of a GOOD layer
- The color begins to fade at the top of the
shank and move down toward the top of the foot.
The yellow on the top of the foot of this hen is
why you cover this area with your hand. This
good layer shows a loss of pigment from the front
of the shank to just above the foot this is good.
45Front of shank of a POOR layer
- This poor layer has lost some pigment from the
top of the shank. If you look closely, you can
see that the color extending upward to about the
middle of the shank. She has not laid as many
eggs as the hen in the previous picture.
46Back of shank of a GOOD layer
- This good layer shows a loss of yellow from
the foot to the hock. In this area, color starts
to the fade near the foot and moves up toward the
hock.
47Back of shank of a POOR layer
- The yellow of a poor producer can be easily
seen in the back of the shank of this hen.
48Hock of a GOOD layer
- Pull the feathers away from the upper hock.
This hen is completely bleached as shown by the
translucent of the scales. A hen bleached
through this point has perfect pigment loss.
49Hock of a POOR layer
- This poor producer has pigment in the hock
scales. Even though she may be bleached in all
other areas, she has not laid as many eggs as one
that has no pigment.
50Toe tops of a GOOD layer
- Remember, pigment is lost from the top of the
toes at the same time that it is lost from the
hock. This good layer is a fine example of
bleaching from this area. Note the yellow where
the foot joins the shank. Modern layers will
often retain pigment here even though they are
heavy producers. So dont get excited about this
condition.
51Toe tops of a POOR layer
- The yellow pigment in the top of the toes of
this poor laying hen can clearly be seen in this
picture.
52- To check for flexibility of the pubic bones, I
will gently press outward on the bone with my
thumb. Notice that my thumb moved over in line
with my finger. This indicates a high degree of
flexibility of the pubic bones. At the same time
run your fingers over the edges of the bones to
feel their sharpness. You should notice an
absence of fat around the pubic bones.
53Flexibility of pubic bones in a GOOD layer
Notice how my thumb lines up with my finger.
Also notice this good layer does not have fat on
her pubic bone.
54Flexibility of pubic bones in a POOR layer
- Gentle pressure on the pubic bones of this
poor layer shows little flexibility. Also, the
bone is surrounded with a heavy layer of fat.
These are both undesirable conditions.
55Rolling abdominal skin of a GOOD layer
- Another indication of good handling quality is
the velvety abdominal skin between the thumb and
finger. You want to feel the absence of fat in
the skin.
56Rough scales and side groove on the shanks of a
GOOD layer
- The absence of fat under the scales of the
shanks also indicates good handling quality.
Note the groove formed down the side of the shank
because of the lack of fat under the skin. This
groove and rough scales indicate there is no fat
in the shank of this good layer.
57Smooth scales and filled shank groove of a POOR
layer
- The groove is filled with fat and the shank
scales fit together smoothly. This indicates an
ample amount of fat under the scales. This hen
has been converting her feed into fat instead of
eggs.
58Body width of a GOOD layer
- This good layer has a body width of three
fingers between the pubic bones.
59Body width of a POOR layer
- This poor layer is only two fingers wide.
60Body depth of a GOOD layer
- This good layer is almost four fingers deep
between the pubic bones and the tip of the keel.
- This good layer has a final body capacity of 3 x
4 fingers.
61Body depth of a POOR layer
- This poor layer is only three fingers deep,
for a body capacity of 2 x 3 fingers.
62Open wing of a GOOD layer
- The feathers of this good layer are old and
worn, and there are no new replacements. This
indicates that she has laid ten to twelve months
without molting.
63Open wing of a POOR layer
- The flight feathers of this poor producer are
similar to those of our good layer. This says
she has had a long laying year of very low
production.
