3 days ago I noticed 8 month old Delaware limping on left foot. Area on top of foot looked swollen and like it was scuffed. Right leg looked like it had 2 small cuts. Thought maybe it had gotten caught in a closing door.? Now today it is limping right leg and there are multiple dark areas on the leg and foot. Almost like a scab but it does not wash off. Legs feel hot but so do the other chickens in the pen. New chicken owner not sure what to do.
