Flocks 24 and 25 each had square feet floor space, .29 square feet cloth or glass surface, and cubic feet air space per hen. The three-year-old hens (pens 5 and 8) and two-year-old hens (pens 19 and 22) were in houses having double boarded, solid walls. The one-year-old hens (pens 24 and 25) were in a double walled house with dfead air space stuffed with straw and with a straw loft. It was exceptionally warm, and so close as to be objectionable. An effort was made to provide all flocks with fresh air by having the windows open much of the time by day, and cloth frames in the windows during the night. While the house conditions were slightly different between the pens of the three-year- olds (pens 5 and 8), two-year-olds (pens 19 and 22), and one-year-olds (pens 24 and 25), the pens occupied by the fowls of the same age were similar. Flocks 5 and 8 (three-year-olds) were allowed to run in similar yards with limited grass forage. The other flocks had constant access when out of doors to alfalfa pasturage. All flocks were confined to the pens during November, December, January and February. Methods of feeding. The attempt to force the molt was by means of restricting the amount of food, rather than by changing the quality of the ration. The starvation period lasted for four weeks. In the first week, the amount of food was gradually reduced to one-half the usual quantity. In the following two weeks, about one-third rations were fed, which were gradually increased in the fourth week till, at its close the flocks which had been starved were given all they would eat.
