So I got my five easter eggers five days ago and was sent home with gallimycin for some eye issues. Didn't seem major and in fact today I thought they looked much better and they were actively eating and drinking. Just an hour ago I went to change their water and this hen was not doing well at all. She's still with us but barely, she is on my lap.. but I do not know what to do. Here's the symptoms.. -some wheezing when she exhales -opens her mouth once in a while like she's licking her beak or maybe trying to breath through her mouth (???) -lethargic and can't keep her head up long Like I said she's been on gallimycin the last four days and in a warm clean brooder with medicated water and food changed daily.
