DESCRIPTION OF POULTRY AND EGGS TESTED 
Chickens 
Rhode Island Red, Barred Plymouth Rock, and White Leghorn chickens were 
hatched in April, 1922, out of good breeding stock. They were raised in grass 
fields where they had free range and secured an unlimited amount of green feed* 
They received practically the same feed from date of hatch until they were 
killed at approximately four months of age. As small chicks, they were first 
fed a mixture of boiled eggs and rolled oats with a commercial baby-chick scratch 
feed. At the age of two weeks the use of the egg-oatmeal mixture was dis¬ 
continued and they were given a mash made up in parts by weight as follows: 
4 parts rolled oats. 1 part middlings. 
2§ parts meat scrap. i part ground bone 
2 parts corn meal. 1 per cent salt. 
2 parts bran. 
This mash was kept in hoppers before the chickens at all times until they 
were killed. As soon as they were large enough to eat ordinary grain, at about 
8 weeks of age, the baby-chick scratch feed was omitted and a feed consisting of 
equal parts of cracked corn and wheat was substituted. 
The Rhode Island Red and Barred Plymouth Rock chickens weighed about 
3i pounds each when killed, and the White Leghorns weighed about 2f pounds. 
All the chickens in the three lots used were cockerels. 
Hens 
Rhode Island Red, Barred Plymouth Rock, and White Leghorn hens were 
used in tests of the flesh of mature fowls. The average dressed weights of the 
hens in each of the three lots were 5, 5|, and 3J pounds, respectively. Some of 
the hens were If years old and others 2f years old, but all had been given 
practically the same kinds of feeds throughout their lives. All had been fed 
the same scratch feed and but slightly different mashes, substantially as follow: 
Mash 
10 parts bran. 
10 parts middlings. 
10 parts ground oats. 
45 parts corn meal. 
25 parts meat scrap. 
Scratch Feed 
2 parts cracked corn. 
1 part wheat 
1 part oats. 
The proportions of the several constituents, other than the meat scrap, varied 
somewhat in the different mashes, but all the feeds were used in each mash. 
Each lot of hens was kept in a good-sized yard where there was more or less 
green feed either in the form of grass or as a growing crop of young oats, wheat, 
or rape. In addition, each pen of hens was fed three times weekly as much 
sprouted oats as they would consume. Approximately equal parts of mash 
and scratch feed were fed daily. 
Turkeys, Ducks, and Guinea Fowl 
The above-named birds were purchased in January, 1923, from a local produce 
dealer. They had been shipped alive from Maryland and Virginia farms and 
were killed at the time of purchase. The turkeys consisted of 4 fat hens weigh¬ 
ing Ilf, Ilf, 12, and 15J pounds, respectively. The ducks consisted of 15 
common farm ducks of fair quality. The guinea fowl were fair-quality birds 
weighing about 2f pounds each, the lot containing 22 birds.
