My 7-8 week old Cream Legbar had her face scratched by a possum on Tuesday night (we caught it and fixed the weakness in her housing). It seemed fine, but then I noticed that it is a green color above the wound. My daughter also thinks her face looks a little more red than usual. Is there something that I should do for this, or should I leave it alone? She's eating, drinking, pooping, and acting fine. It's more noticeably green in person. Is it possibly infected?
