I have a Rhode Island Red Pullet approximatley 12 weeks old. I raised them from fluffy chicks until two weeks when I moved them outside into a small run/shelter within my chicken yard with heat lamp at night only. I wanted the big/little chickens to get used to each other. Two days ago I let the the 7 pullets mix in with my flock of seven two year old hens. Other then a little hogging over the feed, everything seemed to be going okay. Yesterday at dusk one of the pullets was by herself under their raised coop and had made an indentation in the dust, and seemed to not be feeling well. I put her in the coop with the rest of them but was worried because she really wasn't moving. This morning, she was wobbling around in the coop after everyone else came out, I offered her food and water, she ate and drank while sitting in the litter inside the coop. I had to go to work so left her with water next to her. So tonight she was outside with the others, but didn't go back in. She has a gimpy leg, I have brought her into the garage and set her up with a heat lamp, food and water. She ate with great gusto, but in checking her all over it is obvious to me that her leg is broken. A vet visit is out of the question. Any suggestions?
