Hello, this morning I was out with my birds and I decided to let my Muscovy drake in with my three ducks. So he was walking around and then out of nowhere he started attacking one of my Pekins. I had them separated because I didn't want him to try to breed with them because they're only about nine pounds. He's an eighteen pound bird so he would crush them. I scared him back into his pen and looked around at the ducks. Quack quack was the one that got attacked and she was really squinting one of her eyes and that was it. I have seen her Stretch, yawn, swim, drink, go to the bathroom, clean herself and act like normal Quack quack. I'm worried because I don't know if she can see out of her eye. Do you guys think she needs to see a vet? I have also seen her blink her eyes.
