I have a young hen, on whom I used a leg ring to identify her. For some reason, the ring didn't expand as it should have and it badly strangled her leg and became deeply embedded. I noticed her limping, so I saw what had happened, and cut the ring off. I hoped she would recover, but she has not. Almost 3 weeks have gone by since I cut it off, and she is limping worse than ever, and mostly just sitting and hiding. I tried putting a topical antibiotic ointment and bandaid on the leg, although there was no sign of any break in the skin. The leg is definitely still swollen. I don't know what else to do for her. Considering antibiotics, because it seems that it may be a systemic infection by now. Any advice? Thanks.
