A couple months ago, one of our dogs got into the coop and killed most of my chickens. Two of them were severely injured. I nursed them back to health and they are now laying again. Recently I purchased more chicks. I am not in a position where I can separate the 2 adult birds from the chicks. Should I let the adults eat the medicated food I feed the chicks, or should I feed the chicks layer crumbles.
