I'm planning on allowing my broody to raise her own chicks out in the coop with the flock. I plan to keep a close eye on things and separate them only if there is a problem. I would like to feed the chicks medicated chick starter. The rest of my flock eats grower feed, with oyster shell offered. I can put the grower feed up a little higher so that the chicks can't eat that. So, I'm not as concerned about chicks eating the grower feed. However, what if the other chickens eat the medicated starter? Will it harm them in any way?
