One of our egg buyers called us today. Apparently, there was a wild male duck hiding under a bush near the building he works in. He was frantic, so we came out and took a look at it. The duck was a bit dehydrated and has had an eye injury at some point. His left eye is hazy and he has been holding it shut. I started treating it with terramycin, but I am pretty sure he is going to be blind permanently in that eye. I can handle the treating him, but I don't know what to do once I finish treating, should I let him go? Or since he is blind in one eye, should I keep him? He is VERY docile, even more so than my ducks. If I keep him, is there any concerns about him being with my ducks. We have him separated out, and plan on keeping him that way until completely healed.
