A few days ago I noticed an abscess on one of my chickens feet, so since then I've been treating her for bumblefoot. Today I noticed a few of my other hens have the scabs under their feet as well. But they don't have any swelling on abscesses, and they seem completely fine. They still walk and run around like normal. Do I really have to rip into their feet as well? Couldn't they become calluses? I worry that if I try to treat them without any other symptoms I will just cause an infection. I have no idea why they're getting bumblefoot. They don't free range, but instead are in a large safe run all day. I recently got a new coop, but the roosts are just like my old ones. But now I'm hearing round roosts are better... Please advice!
