Today I noticed that my felmale Welsh Harlequin has two sores on her back. They are right under the area where her wings attach to her back. What could have caused this? Could my drake have done this with his claws during mating? She is sitting on eggs right now. She wouldn't have pucked feathers off her back for her nest, would she? What can I put on this so flies don't get in there and lay eggs? I know you have to be careful with birds and insect repellants. I have used SWAT on my horses, but I didn't want to put it on Maggie and make her sick, or worse, kill her.
