I have 3 adult hens and 5 5week olds and too many 2 week old chicks. I live in northern Ohio its about 60-75 in the evenings. The Question is... When can I put the 5wk olds in the coop? Should I keep them in a dog cage for a while first? Then put them together? Should they come in at night? No heat light in the coop. And the big question When can I let them free range? Will they follow the big girls around? Thank You in advance for the help!
