Thinking this is bumble foot, but she's acting fine & not limping. 1st time dealing with this as this is our 1st backyard flock. This is my son's baby! Is this contagious to our other 3 hens or to humans? We just ordered some iodine to do a iodine and sugar wrap. If the scab has no crusty edge, do we still need to pull it off or is this just the beginning so just a soak and wrap may help? Thank you in advance. Our plan was to soak it in a bath, iodine & sugar wrap.
