 The birds consume less feed than those on the floor and this coupled with the increased production made them more profitable than the same number of pullets in the laying house.A number of progressive poultrymen from all over the United States and some in foreign countries cooperated with me in carrying on experimental work with this type of battery and each and every one of them were very well satisfied with the results obtained.In fact, a number of them have since placed their entire laying flocks in individual hen batteries.
