I opened the door and there was a lot of blood everywhere. I found Lovey with blood running down her leg, but most of it had coagulated. I don't think she was attacked, I think she pulled one of her feathers out somehow. We cleaned it with some warm saltwater and we've put her in a box, outside, with a hot water bottle. If she gets worse, we'll bring her in. We can't wrap her leg, because of all of her feathers. I did trim a few feathers, but it didn't help much. We're going to make sure she has water and we're going to give her warm pasta soon. She's quite old, so it might take a while for her to heal. Plus, she has a few other problems like she's underweight, she has lumps on her head (and possibly her body), she has a purple comb and tons of other problems. I've tried treating all of her problems, but nothing ever works.
Is there anything else we can do for her and her leg?
Should I just make sure she is drinking, eating and resting?
