My little Sicilian buttercup, Sadie, got pecked on bad by her sisters last night. Her poor little butt was all covered in blood. I didn't have time to do much this morning, so I put her in the cat crate with food and water and left her under a tree. I just got home, she looks ok, no more bleeding, but I'm worried she will get infected or something. Her butt looks purple and swollen. My brother told me there were house sparrows in there with her all day. I hope they weren't picking on her. Should I bring her inside? Can I rinse her off and add some watered-down hydrogen peroxide?
