I noticed this injury today. It looks like it could be a few days old. She has given no indication she is injured. Unfortunately I when I checked her again it looks worse. The flys and yellow jackets have taken notice and it looks like something has lain eggs in it. She is eating and drinking and otherwise acting normal. We think the male may have accidentally done this while trying to mate with her. There is no smell it just looks awful. What can we do at this point? Clean it and dress it?
