i have a broody buff orpington with eggs due to hatch on the 29th of this month! shes broody in a nest box with 4 eggs under her. my questions are, should i change the whole flock to unmedicated chick starter when they hatch? or should i just let the chicks free range with their momma and put a feeder outside with chick starter in it? or just let them free range with no feed? i know i cant feed medicated chick starter because itll affect the eggs i would get from the rest of the flock. this is my first broody hen so im not experienced on this subject. also, what should i do about the chicks sleeping? because the nest box that the broody hen is in is about 2 feet off the ground and the chicks wont be able to get in it to sleep at night. will the momma naturally keep her chicks warm at night on the floor of the coop on the straw bedding?? please help!!
