[HayleyCrum]

one of my ducks is having an issue with her having a foamy eye, i just need to know how to treat this? the picture doesnt show it being foamy but you can tell its not normal

Does she have clean water to dunk her head? Terramycin is an antibiotic ointment I have used on my duck's eyelid- I got it at my feed store, but it's everywhere: https://www.amazon.com/Zoetis-Terramycin-Ophthalmic-Ointment-8-Ounce/dp/B00063KGUK
