Hi all, I will give you as much info as I have in brief. I have a yr old white EE who is a great layer. She is a bit on the thin side, but has been since the beginning because she is streamlined to never be caught! I have never seen such a fast chicken!!! Anyway, she is dozing all day and seem to have trouble keeping her eyes open. I have checked her for mites and egg binding...nothing. Her eyes are not swollen and her mouth and nose seem fine. She does still eat. She is usually always on high alert (should have named her the general), so the sluggishness over the past few days is really unlike her. I have Tylan 50, but am reluctant to use it without other symptoms. Any thoughts would be much appreciated. Thanks!
