This morning we found my hen, Daisy, knocked out cold and laying on her side. It turns out she has a giant gash around her tail area. She had on a knit sweater because she has a bald spot, and it appeared the sweater was torn off as well. She is smaller than the other chickens, her feathers were pulled out when she was attacked by a turkey and they have yet to grow back (if they ever will), so they bully her from time to time. But she's quite strong and loud, she also is my best layer. But I don't believe they hurt her, perhaps the sweater for caught on something and she somehow hit a sharp edge...but well she now has a deep cut and I don't know if she needs stitches. It does seem really bad, I think that's bone I can see too, so stitches are needed...right ? I did soak her in a solution and cleaned the wound up. It's currently covered in neosporin and bandaged. Any advice would be helpful! Thank you! Edit: this morning she seems to be eating and moving around fine. She also poops fine, the cut was right next to her bum area, she slowly squats first, which I figure is to help with the pain. But I still wonder if stitches are needed, or if I keep the bandages bound securely, could that be enough ? Edit: Also, is there anywhere I can get antibiotics other than the vet ?
