I have a flock of 8 free range with one of them a 1 year old rooster (leghorn I believe). I came home to find my rooster had ripped two of his toe nails off, one of which bled so bad I wrapped it for the night and will check it in the morning. I have no idea what he injured himself on but I would like to avoid any re-injury. Any thoughts as to what he could have hurt himself on? They all get along peacefully and the hens submit to him with no issues.
