Our adult Sultan hen started having draining eyes that would stick closed overnight - we would gently clean them with warm saline & cotton balls so she’d be able to see in the morning & as long as she could see she’d be up & eating like normal. We brought her in the house a couple days later, as it wasn’t getting better & we didn’t want to infect the rest of the flock or have her picked on. Now her whole face is affected & she’s not a happy girl. We’ve cleaned her eyes & applied ophthalmic antibiotic ointment daily, but it’s not resolving. Please help!
