Hi - recently we had a fox kill several of our chickens and maimed 3 of them. We thought the 3 injured wouldn't make it but 2 of the 3 appear to be fine after bandages and constant care. The 3rd is eating and drinking and happy to see you but seems to have broken ribs? It can stand up but when it goes to walk it falls forward head over tail and then can't get up again without help. It's been about 10 days and each day she seems to move more and more so I'm thinking she broke bones and they are healing. Any suggestions perhaps for some sort of sling to help her balance?
