My broody hen lost interest in her other eggs when the first chick hatched, so we only got one chick. It is now 2 1/2 weeks old, healthy but with it's momma in a separate pen. We have 6 hens and a rooster. Problem is, the separate pen is outside, and the days are getting down to 50's. I picked up 8 chicks last week from a local breeder that are in an inside brooder. When is it best to get the chicks together? Is the one little chick in danger from the cold? It runs around in the 50 degree weather, but the other chicks are still maintaining 80 degrees. It will be getting colder soon. The age of the new chicks seems to be 1 week to about three weeks. The hen seems to be caring for the chick thoroughly, but showing some signs of stress. There were several feathers in their confinement yesterday, which is new. What should I do?
