I got 4 new chicks by total surprise even to myself. The tack store had buff orpingtons, barred rocks and cuckoo marans. All breeds I've wanted. I have them on a good medicated feed. I've been very careful to not handle them then go handle my hens. How do I need to be sure not to put my hens at risk? I love them. I would get rid of my new chicks before hurting my girls. And just cause they are cute!
