chopper, thoroughly mixed with about six times their bulk of 

 rolled oats. Beginning about the sixth day, the following grain 

 mixture may be given : 



PARTS BY WEIGHT 



Cracked wheat 15 



Pinhead oatmeal 10 



Finely cracked corn 15 



Finely cracked peas . 3 



Broken rice 2 



Fine grit 5 



Fine charcoal 2 



As soon as the chicks can eat whole wheat and coarsely 

 cracked corn, they should have these instead of the finely 

 cracked grains. 



When the chicks are taken from the brooders and put on 

 range, they may be fed entirely in the hopper, since they have 

 an abundance of exercise in chasing bugs and scratching for 

 worms. Cracked corn, wheat, cracked bone, ground oyster 

 shells, and grit may be placed in separate troughs, as is also the 

 following dry-mash mixture : 



PARTS BY WEIGHT 



Wheat bran i 



Corn meal 2

567. Saving eggs for hatching. Eggs for hatching purposes 

 should be put under the hen or into the incubator as soon as 

 possible after they are laid. When it is necessary to save them 

 until the number desired has been accumulated, they should be 

 kept in a cool, dry place and turned once every day. Eggs begin 

 to develop into a chick very slowly at 68 degrees F. The rate 

 of development increases until the temperature reached is 103 

 degrees F., when the rate of development becomes normal. 

 Slow or abnormal development injures the vitality of the embryo 

 chick. Eggs saved for hatching should therefore be kept at a tem- 

 perature below 68 degrees F. A temperature between 5 5 degrees 

 and 65 degrees F. has been found to be the best for this purpose.
