I purchased five 1 week old turkey poults 18 weeks ago. 3 of the 5 had one eye that was only slightly open and they could not see out of the eye. Over the next 18 weeks the eye issue has not resolved; however otherwise they seem to be fine. They all have a swollen lump over they eye that is closed. I don't have a vet in my area that looks at turkeys. Does anyone know what this could be?
