The condition of his back toes is due to damage from fence/pen fighting.
You can put some oil, ointment or vaseline of those back toes and scales to help smooth them if you wish.
Foot in the photo, I suspect may have been fractured or injured at some point and has just healed that way.
If he's getting around o.k. then I'd not do anything drastic or invasive. Soaking in a warm epsom salts bath to help reduce swelling.
If he's kicking wired occasionally, he's going to continue with soft tissue damage and swelling.
