I have a 8 month old Muscovy duck (girl) who is keeping one of her eyes closed a lot of the time. She can open it when she wants to for example whenever I go out to check on her but most of the time it is shut.
I only have 6 ducks (which I keep as spoilt pets) and they have 2 small paddling pools in their pen and one outside it to play and wash in which I clean regularly. She has been like this for about 5 days and I have cleaned the pools out everyday and locked the drakes out so she can get preference in the clean water.
Finally I have taken her and put her in our bath in the house in clean warm water a few times and made sure she had a good wash. Whilst she was in the bath I had a look at her eye and it looks fine.
She is eating and exploring with the other ducks and whenever she goes in the clean water she has a good flap and seems to enjoy herself.
Any idea what the problem could be.
