My poor chicken's foot has an infection. I think it's bumblefoot, but there is no scab for me to open this foot up and drain the infection from. I don't know what to do. One time I attempted to cut into it as is, but I "chickened out". I've treated bumblefoot several times, but not without the black circle scab to drain from. I can tell it's hurting her, but she's still getting around okay. It's gradually getting worse though and if there is a way I can treat this, I'd like to try without investing in a vet. Her comb and wattle are fading in color too. Not sure if this is a sign that it's getting worse. Thank you for your help.
