 When and How l0 Call 3
hi \\‘ht·n a bird stops laying in the summer she usually starts molt-
1; mg, The later a hen lays in the summer or the longer the period
W- over which she lays, the greater will be her production, so that the
lt- high producer is the late layer and hence the late moulter, provided
ll? she receives milk or tankage thru the summer, to balanee the ration.
The early moltcr is not the early winter layer. The high layer
hl ll$llllii}` retains her primary wing feathers until September or Oe-
nd tohel`.
ill The depth ot yellow color should be observed by daylight. When
M"' a hen starts laying the supply of yellow coloring matter obtained
lm ll‘t)lll the food eaten is diverted from the skin, beak and shanks to ·
*1* the yolks of the eggs being formed. The yellow pigment already
stored in the skin, beak ami shanks gradually fades and the parts
become white. The changes occur in the following order;
The color of the \'liN'I` changes very quickly with egg production
" so that a white or pink rent on a yellow-skinned bird generally
means that the bird is laying, while a yellow vent means a bird is
not laying. It should be recognized that all yellow color changes
Lite dependent on the feed, coarseness of skin and size of bird. A
heavy bird fed on an abundance of green feed, yellow corn, or other
heavy material that will color the fat deep yellow will not bleach ottt
me nt·arly as quickly as a smaller or palcr-colored bird.
·y¥· The color goes ottt of the lil·ZAl{, beginning at the base and grad-
llltl ually disappearing until it finally leaves; the front part of the upper
l Y beak. The lower beak bleaches faster than the upper, and should
l’lll‘ be used where the upper beak is obscured by horn or black. On the
Fill" average-colored, yellow-skinned bird, a bleached beak means heavy
ll" lll`t>dl1Clio11 for at least the past four to six weeks.
HM- The SHANKS are the slowest to bleach out and hence indicate
a much longer period of production than the other parts. The yellow

mi ?ll`€ the last to bleach out anti may generally be used as an index
  to the natural depth ot yellow color or the bird. A bleached-out
mug Shank usually indicates fairly heavy production for at least 4 to 6
hm. months.
