This morning when I went out to feed the girls, my daughter noticed Zelda's eye was close and she wouldn't open it. At this time, she is moving around fine, not lethargic, and her eye is not swollen or anything. She just wont open it even when we entice her with treats. I don't know how long it's been this way, not more than a day or so, if anything. Since I know nothing about treating a chicken, I am looking for some advice. Should I separate her in case it's the start of something contagious? Should I try to open it? Should I put some over the counter med on it? Warm compressions? Or should I just leave it? thanks!
