I rescued several broilers from people who didn't have a clue and most of them did not even know how to walk they were so over fed and barely had room to turn around. So they have mostly gotten much better, actually running sometimes! But many of them have the black callouses on their feet, about the size of a quarter to a half dollar. Don't hate me but I want to butcher about half of them ( all the males for sure) but if they possibly have bumble foot, ( we scrubbed them and put an antibiotic on all of them the first day we got them) even if not in pain from it, would they be ok to eat? I also would like to try non surgical treatment. Poor things have had a hard start!
