https://photos.app.goo.gl/AaW9wQUE8bAfs4DE6 This leg is pulled up and my rooster is standing on the other leg which looks worse IMO. https://photos.app.goo.gl/kLArpeCGKKPGcyq18 Problematic Leg: https://photos.app.goo.gl/vXLTMiNxja3DvPLu8 Other leg: https://photos.app.goo.gl/eUcbM1583UjmPMKr5 I think it is missing that huge nail and i see blood. https://photos.app.goo.gl/Wq3ZMa23jkfnWZeq8 https://photos.app.goo.gl/6VoNeAyKYEUGtZwFA Not sure if this leg looks normal? https://photos.app.goo.gl/9BQZNzUtji3EJ9KS6 https://photos.app.goo.gl/hKg7SGTau78Ujuz29 Here you can see like some mold on leg: https://photos.app.goo.gl/DcRHJdnWG2DJbjBb7 https://photos.app.goo.gl/CqXjxged818bF6cf8 My theories: There is a very low probability for the predator like a fox or anything like that because 2 dogs are living with chicken and I am sure nothing can go through them. But I see a missing nail on one leg and some blood. The second theory is frostbites, but yesterday was not that cold, in fact, a few weeks ago was colder and this is not the first winter for this rooster. Weirdest theory is that maybe my rooster jumped on the sheep and somehow stuck his nail in the sheep wool and maybe that is hurting him? At this moment i put him in a corner and he is resting, but if these are frostbites or something like that I probably need to do something. I know I put lots of pictures but I am not sure which one is giving the best details of the problem. Please gime any advice.
