Personally I think it would be better to separate the younger ones and the older ones. The hens will eat all the chick starter and not want to eat the layer pellets anymore. If the broody hen is not the dominant type, the older chickens could dominate the feeders and not allow the little ones to get any food. I keep mine separated for the first two weeks or so. When the chicks are a bit larger, I let them all out to free range together for an hour or two in the afternoon. The chicks learn now to integrate into the flock without having to compete for food with the older ones. Plus they have more space to get away from the meaner ones if they get chased. When they are 2 - 3 months old they will be big enough to defend themselves and go in with the flock.god I am so excited!! My two bantams should be hatching out a lone baby chick hopefully this weekend then its off to the feed store to get her some more chicksbut I had a question my grams only ever fed her chickens scratch but I wanted to feed the new chicks medicated chick feed....how do I do that without the chicks getting into the layers feed and the layers getting into the chick feed without locking up the hen(s) and the chicks. I still have my old brooder that I set up when I raised the birds I have now but both mama hens are use to free ranging if I locked them up in the brooder with the chicks until they where feathered do you think they would freak out?![]()
