Our Buff Orpington is constantly going broody, so we decided to get her a couple of day old chicks to mother. She took to them right away, and is so happy with her new duties. But, this morning I found one of the chicks dead in the coop. I don't know whether I can replace the lost chick, or will she reject it now that she's been mothering for a few days. I don't want to buy her a chick she won't accept. Anyone have any knowledge or experience on this matter? I'd really appreciate some advice! Thanks so much.
