I have 4 male ducks about 5 month old a Pekin; Donald, 2 Rouens; Heath and Jack and a Buff named Arttie. Donald and Arttie are rather mellow but the Jokers are a riot. Today Jokers beaked Arttie in the eye he was separated but later towards the night while we put them up he was hiding in the ivy bush and wouldn't come out. As soon as he did I noticed his eye half closed, a bit teary and not foamy but kinda. make a note that they are completely healthy well fed ducks and i just want to know how to treat his eye.
