This morning I found our drake, Piper, sitting down with both his eyes bleeding badly. He cannot see. One eye is red (though he usually keeps it closed) and the other looks swelled up, with whitish slime (discharge, I suppose) in it and coming out. His bill also has a deep scratch in it and was bleeding slightly... I can't tell if it went all the way through, though. Most likely it was either a rooster or the guineas. Now he's in a pen with our other duck, who is keeping him company. He is walking around sometimes but spends most of his time sitting down. I have not seen him eat or drink (because he can't see the dishes.) What should I do? All we can think of is to put antibiotic ointment around his eyes. Should I force him to eat and drink?
