OK all u chicken veterans! We have picky pullets 2 are about a month or two from laying we think. not sure exact age, we adopted them as young pullets. 2 are about half the age of the older pullets. and we have one little BB bantum rooster. Thet do not like the corn in the scratch feed ( recently heard about the corn and heat thing) maybe they knew that already. won't touch the laying feed 17% protien. Any suggestions?
