About a week ago I noticed my 17 week old buff orpington was limping. At first I checked her out didn’t see anything and figured maybe she just hurt herself jumping or something and that’d it go away in a few days. She’s eating, drinking, and pooping normal. She will still run for treats, but holds her leg up if she’s just standing and lays down to rest a lot more. She’s also been stepping on her foot and almost tripping herself. She seems to have full range of motion, I’ve seen her stretch her leg out. I checked her out again yesterday and I found a little red patch on her leg that’s a little swollen. I gave her an epsom salt bath and put on a bandaid with Neosporin, I also gave her some Nutri-drench. What could this be? Thank you!!
