I have a four month old barred rock pullet who started limping about three weeks ago. Yesterday I noticed that one of her feet is hot to the touch. There is no lump, swelling, or discoloration. I can see no evidence of a wound other than her "thumb" pad on the affected foot is a little tougher than the other. She has no other symptoms - she is eating well, very lively, flies/hops up to and down from the roost. She lets me palpate the foot with no objection and it doesn't seem like anything is broken. As of last night I have her quarantined in a small pen to prevent further injury and because I read that bumblefoot can be contagious. I thought about treating for bumblefoot as described elsewhere in this forum, but there's nothing to do surgery on. Should I administer antibiotic? If so, what, how, and how much? Will a topical antibiotic ointment do any good? Does anyone have any other advice to share? Thank you for any insights!!
