Hi, I have an almost 4 month old red sex link chick. She is laying in the coop kind of toward one side of her body, with both eyes closed, scratching herself a bit and lets her head droop then pulls it up again. She has not yet laid any eggs. I have 6 chickens and i haven't seen any of them scratching or biting but i have not done any treatment for parasites - i've had the birds about 2 months. Any advice? She is in a spot where it will be hard to reach her under an a-frame coop, would have to have my husband lift it up to try to get to her. Thanks!
