So I plan on starting my chicks on chick feed inside. Until 6 weeks, then I'm putting them in the coop in a fenced off area. Until 9 mabye ten weeks? Do you think that would be a good age to introduce them to each other, since they have been in the same coop, but just fenced off? And then what would I feed them all? If I feed the layers and chicks flock raiser, I would need to give the adult hens oyster shell. But, how do I feed them that without the little chicke girls eating it too? Since its bad for their kidneys. Any help is greatly appreciated!!!
