I put a couple orpington chicks under my silkie last year and it worked for me. She hatched 4 of her own and I added the extra the next day. She didn't seem to notice the difference:) however it might depend on how many chicks she can keep warm. Just letting you know its a possibility but not...
This is the only thing I could ever do in this situation. Its not possible for some people (including me) to take any creatures life. I've had a couple chicks surprise me and get better! Good luck to you in whatever you choose to do :(
Has anyone else had trouble eating eggs. After you've incubated/hatched chicks? I know this is stupid ...I love eggs but now they make me kinda icky :(
