My dog got into the chicken yard again 3 days ago and briefly got hold of one of the hens. She doesn't have any open wounds but won't bear weight on her right leg. She will occassipnally stand, hop on her left leg and seems to use her wing as a crutch. Idon't see any obvious break. I have her isolated in a 4x4 area in the chicken tunnel and put her in a pet carrier up on the roost with the others at night. She is eating and drinking small amounts. She won't be going to the vet. Is there anything else that I can do to help her try to recover?
