Last week I posted about my BR Pullet - about 22 weeks old - suddenly developing a pronounced limp and then proceeding a few days later to just sitting in one spot - not moving - not able to walk. She is not paralyzed - she can still flap her wings and move her feet and legs and is able to clutch my fingers with her toes - there is no evidence of injury, no swelling or heat. She is laying an egg every day and is bright eyed and talkative - just won't stand on her right foot - the toes are are all very close together - they were curled back but seem to be straightening out now. Initially, I thought she may have been injured by one of the roos taking a ride (bad roo). I don't know - I don't have a coop - they are in a 8x8 wire pen on pine shavings over a rubber floor mat. Does Bumblefoot always result in an open sore? I'm a new chicken mom and don't know all there is to know - I know I'm finding out more than I thought I needed to know. Would anyone recommend following Gail Damerow's suggestion for injecting 0.5ml penicillin into the foot or is that a bad idea to treat for something not confirmed?
