Hi, My buff orp is sick and I'm trying to troubleshoot why. She has intermittant black spots on comb, loose stools and her respirations are somewhat labored. She's been showing these signs off and on for a couple months, but yesterday, her comb got very dark and she's loosing ground. A couple weeks ago, I noticed her standing on one foot. I could see that she had a slightly enlarged bulbous thing between 2 toes. I picked her up and felt it, and it was soft, with no breaks in the skin, and it didn't seem to bother her. Her legs have seemed extra red to me lately too. The bulb thing might just be a variation on normal.......I just don't know. If its not infected, its not bumblefoot, right? Do sick chickens ever have ankle/foot edema?? Thanks for any insights you might have.
