UPDATE
I’ve been taking care of her for several days and she’s been doing a lot better on the penicillin (the blue under her skin has completely receded, unknown if due to circulation or blood poisoning)
however, physical examination of the wing seems to show that the bones are not damaged. The wound area is still just as swollen and the abscess has grown, in at least small part because she’s an actual Houdini who keeps picking at it every time she gets out. I’m thinking it’s either infection (I know it’s solid in chickens) or a tumor and I’m not sure which. The skin/fat pull away from it when there’s no clot in the wound. I tried gently squeezing from under it but it didn’t budge.
She has a healthy appetite and eats/drinks a lot once I pull her out of the wrap. I’ve been gently dabbing at the wound to clean it when I pull her out.
note that the yellow in the picture is due to wiping with Betadine and the dark clumps outside the wound are from the various medications sticking to her , her skin itself looks fairly healthy.
