Hello all I woke up today and one of ny hens is favoring her left eye. It looks runny but i dont see puss. She is trying to keep it closed but the other eye appears fine and i dont see any similar symptoms on my other 9. Before I take her to the vet should I try flushing the eye? What is the best way to do this and can I hurt her in any way or make it worse by trying? Thank you!
