You'd be amazed at the horrific looking wounds that chickens can recover from! She may be in shock, so keep her in a calm, dark spot for a day or two, somewhere convenient for you to observe her. Consider antibiotics. You cleaned the wound out with peroxide, that's okay, but don't use peroxide a second time, as it's strong enough to kill living tissue. Saline or water works well for secondary cleansing. A spritz of blu-kote (whatever color you like except red) will go a long way in camouflaging the wound from her flock mates. If you separate her from the flock, it would be better for her if she's still within sight (and sound) of her mates, as it will not only comfort her, but will make reintroduction back into the flock so much smoother. For chickens, out of sight is out of mind, and if a flock member is out of sight for upwards of a few days, they'thare likely to find themselves at the bottom of the pecking order when they return; many 'old friends' will turn a cold shoulder. Once the wound quits bleeding and is appropriately disguised and has some scab developing (chicken scabs look different than human scabs, they're like dehydrated skin). Can rub some triple antibiotic ointment (the kind without pain relief) onto and into the wound. For pain, you can offer her aspirin. Dosing and contradictions are noted on the following website

Praying for an amazing recovery for your feathered family.
