Is this rooster still very young! Maybe in time your hens will like him better. Or, they can't believe that this strange looking little guy is actually a rooster?!

There's no excuse for his condition when you found him, but he likely was a jerk, and that's why he was tossed out.
Some roosters are just going to be obnoxious, and unfixable.
You did a good deed, and he's in a better place, but he's just not a keeper.
