I have a 2 or 3 year old rooster. I noticed when he jumped down from the porch railing he started to limp. I caught him and checked his feet and found there's 2 or 3 small scabs on his foot. His foot isn't swelled and after I set him back down the limp was gone. Does bumblefoot present without swelling? He doesn't limp otherwise I would of noticed this sooner. He's always jumping on the railings to get to the highest point so he can crow. I don't want to remove these scabs and introduce infection if there's no need. What should I do?
