but last night I read in a book, let me go pull the book.....STAND BY....ok found it...let me post it straight out of the book:
starts with the SKIN: skin is think over much of the body, except the COMB, WATTLES, EARLOBES AND PREEN GLAND.
PREEN GLAND stores fat, upon irradiation by ultra violet light it forms vitamin D3 which is worked into the skin by rubbing it with the beak.
YELLOW SKIN is the result of the HYDROXCAROTENOID PEGMENT: XANTHOPHYLL, from the feed...corn, alfalfa and marigold petal.
YELLOW SKIN IS ALSO: the pigment which is lost in parts of the skin as the HEN LAYS EGGS.
The number of eggs necessary to bleach various parts of the body are given in the chart. As the HEN LAYS, all the pigment is diverted into the yolk so it leaves the body, but when the hens stops laying eggs, it returns. So what its saying is the hen loses color in her body...
VENT 1 EGG
EYE RING/EAR LOBES 9-12 EGGS
BEAK STARTING FROM NEAR THE FACE TO THE TIP AS FOLLOWS:
INNER 1/3 11 EGGS
INNER 1/2 18 EGGS
INNER 2/3 23 EGGS
AND IT GOES ON AND ON...WHOLE BEAK 35 EGGS LAYED
BOTTOM OF FEET 66 EGGS
FRONT SHANKS 95 EGGS
BACK SHANKS 159 EGGS
TOPS OF TOES 175 EGGS HOCK JOINTS 185
let me see if I can find that post I talked about also....Ive just started this book and read on the yellow skin. Ok, here is what I posted a few wks back and nobody read it...
