two and one-half minutes, since the poults are now obtaining more 

 feed on the range in the form of insects. 



12. About the same time sour milk is introduced. It (whey and 

 curd well mixed) is placed in shallow pans or in troughs, scattered 

 about the range. It is at first given each morning and night at 

 the rate of about one quart to each forty poults, and is gradually 

 increased in amount until by the beginning of the fourth month 

 one quart may be given for every twenty birds, each morning 

 and night. 



13. During the second month, which is the critical period for 

 young birds, the feeding is continued about as in the latter part 

 of the first month. But, after the age of about six weeks, the 

 number of meals per day may be reduced to two. Green feed in 

 the form of chopped carrot tops, onion tops, or lettuce should be 

 given in abundance; it should comprise at least one-half ot the

ration for each meal. The time limit remains at about two and 

 one-half minutes. 



14. When the poults are about six weeks old the nest or brooder 

 coops should be replaced by larger houses made of lath and covered 

 partly with roofing paper. Such a house may suffice until the 

 poults are about three or four months old. These may be about 

 three by five feet, and three feet high at the apex. Family houses 

 should then be given up and all the poults, with their mothers, be 

 brought together in a single roosting shed. 



15. The feeding for the third month is like that of the second 

 except that the amount of milk is gradually increased and that 

 grain mixture of eciual parts of cracked corn and wheat may be 

 gradually substituted for the chick grain. 



16. As the autumn months advance and insect life disappears, 

 the time limit may be lengthened to three or three and one-half 

 minutes. In rainy weather the noon-day meal may be added and 

 a four-minute period allowed. Rolled oats may be omitted and the 

 ration made to consist of grain mixture with an occasional feed 

 of rolled oats or bread and milk. A mash may now be allowed 

 containing some beef scrap.
