I received the drops for this chicken whose eyes were swollen and she couldn't see out of them. Within 3 days of using the drops which cost a lot less than terramycin by the way, she could see out of one eye. The bad eye in a week I could see yellow in her eye and with a small push on the eyelid and it popped out. My hen is now gaining her weight back and able to get around by herself again. Thank you so much.
