I have a 3.9 lb hen and and 8.2 lb roo. He tends to mate her the most because he can squish her, the other 5-7 lb hens aren't as cooperative. Can he give her a sprain? I checked her feet and there were no lesions, they were not swollen. Eyes weren't weird from Marek's and no one else has shown a sign. They will be a year old the first week of Sept. No hot areas. She seemed ok with me moving her "knee" but didn't like me moving her thigh on the foot that she doesn't want to stand on, so I guess that is what must hurt. The bones are not broken.
