Eve - we have been working on the assumption that she had a sprained leg which is why we've kept her in the cage in the house to hopefully let the injury heal while she rested. She was limping but otherwise seemed fine.
We don't have a good chicken vet although i can try and find one on Monday. The question is whether it's kind to keep her going when she really can't move without falling over now. I'm really not sure what'sthe right thing to do
