Well I have read on here of hens just hearing other chicks and wanting to mother them and taking them right away. So I don't know about your hen. But it might be worth a try just to let her hear them and see what happens. She might go crazy trying to get them thinking they are hers and she lost them. I don't think it matters if you try this or not. I would hope the putting them under her at night would work. Either way I Hope it works for you. It is so much easier letting momma take care of them. I love watching her teach them to scratch ect. When are your new babies gonna arrive? It is pouring rain here and cant even let my girls out yet. I bet they are down there waiting on me.
Later Cindy
