Looks like Bumble foot to me. My rooster had this. Soak his foot in Epsom salt and warm water.
Look for a dark scab. Sometimes heavy roosters get it from hopping down from their roosts. Is he limping on it?
Soak the foot in a peroxide bath, and see if there is a scab or a sore. It will bubble at the hole, no matter how small. If there is, then follow the bumblefoot directions. If you can find a scab, you have to pull the scab off, and mash it to get the puss and ick out of it. If not, then you may have to lance it. Good luck!
He is limping and it looks like a sore where his toenail should be. Going to soak it and see if I have to lance it. I read the article on Bumblefoot and I may have to get help to lance it. Thanks so much for all the help.
