I just got a shipment of chicks today and one of them won't stop scratching her eyes. She'll pause for a minute or too then run into walls and everything else trying to scratch them. I checked her eyes and I don't see anything in them and I flushed them thinking she has something in them but she's still scratching. I'm not sure what to do at this point. She's really wearing herself out and I don't want her to get trampled. Should I separate her and keep trying to flush her eyes or should I leave her in with the other chicks and hope she stops?
