For quite some time now one of my hens has some problems with her feet. She walks normally but when running she limps pretty hard. I can't tell if it's scaly legs or bumblefoot.. or anything else. Pictures explain it the best: That pinkish area in between the fingers is a tiny bit swollen too. It's been like this for weeks and it didn't change. One day she started limping when walking too, so I applied some vaseline and the limping went away but the bulkiness didn't. Any idea what's going on?
