I think I may have waited too long to start introducing mama and her three chicks to the flock. They are almost 9 weeks old and are separated (but in view of) the rest of the flock. Today I put in a small run for them to start getting used to it outdoors (I free range) and mom was thrilled. I thought she would be out there showing them bugs and grass but instead she's pecking at the chicks a bit as if she's annoyed by them. So they have decided they don't want to be with her out there and are staying inside, and she could care less. Today mama laid an egg. Have I waited too long? I thought she would show them the ropes and protect them when I let them all out with the flock, but now I have serious doubts. What should I do? Are they going to have to fend for themselves at this point? Any suggestions would be greatly appreciated.
