I have a cockerel with a bump on eyelid he is not sick and he gets vitamins in his water daily right now he is up in a cage.
Trying to post a pic of it not working!
We had ring worm on our 4-H steers and I sprayed the ringworm with athletes foot spray works wonders dries it out cause its a fungus they got it from getting in the pond in the summer time.
I have a BrownSwiss the same way she is spoiled!! She not as bad as she was after she calved. I would take a small stick and smack her on the nose or the top of her head polled area. She knows she can get away with this and she going to keep doing it until she knows who her boss is.
