STANDARDS AND RATIONS FOR POULTRY 263 



practical to compound feed enough for a few days. Supposing 

 we had enough laying hens, weighing 5-8 Ibs., to make a total 

 live weight of 200, 300, 400 or 500 Ibs. Our standard for laying 

 hens of this weight would be multiplied by 2, 3, 4, or 5 as the 

 case would be and the feed balanced accordingly. Example; 

 the standard for laying hens weighing 5-8 Ibs., is, dry matter 

 3.3 Ibs., ash 0.20 lb., digestible protein 0.65 lb., digestible car- 

 bohydrates 2.25 Ibs., and digestible fat 0.20 lb. Let us sup- 

 pose all our laying hens total 300 Ibs. live weight. Then to find 

 the standard for 300 Ibs. we must multiply the standard for 100 

 Ibs. by 3.

Chick Rations. Chicks should not be allowed to eat too much. 

 Some of the methods of feeding chicks used in the Maine Ex- 

 periment Station taken from Farmer's Bui. 357, follow: 



I. "Infertile eggs are boiled for a half an hour and then ground 

 in an ordinary meat chopper, shells included, and mixed with 

 about six times their bulk of rolled oats, by rubbing both to- 

 gether. This mixture is fed for two or three days, until the 

 chicks have learned how to eat. It is fed with chick grit, on 

 the brooder floor, on short cut clover or chaff. 



"About the third day the chicks are fed a mixture of hard, 

 fine broken grains, as soon as they can see to eat in the morn- 

 ing. The mixture is :
