Hello all. I have 4 hens. One, a black sexlink, seems to be injured. 3 days ago, she was absolutely fine. The next day, I noticed she hadn't come out into the open pen, so I looked for her inside the shelter. She was sitting on the ground. She can't seem to stand. This has not changed since then. I checked her over quickly, and can't see anything obvious. She looks otherwise well, eats and drinks. She's not laying eggs that I can tell, but I suppose that's expected. I just can't figure out if she hurt herself, and how, or if this is a disease? But I wouldn't expect the last, given that she is still alive, not poofed or swollen or anything. First of all, might anyone have any ideas what happened to her? Secondly, what can I do to help? If her limbs were injured, could I help them get better? Perhaps I could make her a plank of wood with 2 holes to slide her legs into so she isn't on them, set her up with food and such. Any advice appreciated. Thanks.
