I have a Muscovy duckling with one eye open and the other eye which is closed. The closed eye kind of was underdeveloped, but has the other normal eye. The bill of the duckling is a little bit offset and crooked but is eating and drinking fine. The duckling is about a week old and I hatched it myself. Out of 24 eggs, i only got 4 that hatched. I would be severely disappointed if i had to cull it. What should I do?
