I'm not sure how my little white leghorn hen cut her comb, but it covered her head in blood. It's no longer bleeding, but I can't put her back with the flock until I clean it all off or they'll pick and peck the heck out of her. I used warm water but it only seemed to dilute the color of red on her white feathers. Can I use peroxide? Is there something better I could use? There's no reason to keep her in the crate in the house other than the dried blood/color of red all over her head.
