Hello, Well, this poor little duck has not had a good time of it. This is one of 3 ducks I hatched out and had to give away. I picked 2 of the 3 back up last week. This one had an eye infection/damaged eyelid and a swollen cheek on the right side. The swelling has gone down and the eye is much better now. Missing part of the left upper eyelid. Anyway... I did notice a dark spot on one of her feet when I picked her up. She and her sister had been eating mulberries and playing in the mud when I got them. Thought it was just dirt at the time. My mistake big time. The spot does not appear bigger than it was, the duck walks normal. I believe the infection to be older and partially dried out. There does not appear to be any swelling. Today I cleaned the area and put some antibiotic ointment on it. Then wrapped in stick to itself tape. I did attempt to puncture the area to see if there was any infection on the inside, but nothing came out. My plans are to clean the area daily, use the antibiotic ointment and wrap. Unfortunately she will be getting wet as I have no way to keep her out of the water pan. There may also be an area that needs attention by the back toe nail.
