My 3 year old Black Australorp Miss Bella has a leg injury and I am not sure if it is broken or just sprained..We built them a new coop yesterday as well as a new run..this morning I went in to check on them and give fresh water...as per routine they all came running when I go in and I did not notice a small board beside me..I must have hit in and before I could stop it the board fell and landed on Miss Bella..it did not fall right on top of her and the side of it landed on my other RIR Miss Gretta..they all went running including Miss Bella. it was a few moments later when I noticed her holding up her leg and kind of pecking at the bottom of it. I watched her and she kept her leg up and would not put any weight on it. I went to try to pick her up and she ran off. It seems like she puts it down at times but non weight bearing at the moment. I picked her up and looked at the leg..did not see any signs of a break and she did not flinch when I tried to move it...but the foot seems limp. She did not curl her toes around my hand like her other foot did but the leg did not just fall and hang there..I have her in a small pen inside just to give her a break from the rooster. Is it limp because it hurts or could there be something more? I saw her put it down to hobble on it and I know she ran off..I am thinking she may have sprained it running off. Could it be broken or just a bad sprain..either way how do I treat her? Leave her on the small pen for rest or put her back out and let her heal by herself? First time with injured hen..not sure what to do. Our vet is not in until saturday(the only Avain vet around) HELP!
