I bought 6 leghorns last night (1 day old) and I put them in with my 4 week old girls, everyone seemed fine last night but this AM I had one not moving! I picked her up and really thought she was dead. I used the blow dryer on her and then put her in a little towel and on a heating pad. She started making some noise, I put some water with electrolytes in a dropper and gave her some. Is there anything else I can do? I'm really worried she isn't going to make it. and do I need to keep them separate?
