I have a very large Australorp that was hatched just this past Spring. She has been eating, drinking, pecking around, normal chicken business every day. Last evening when we went in to feed/collect eggs, she was on the box tops completely unaware to our existence and "asleep". I picked her up, she opened her eyes and looked at me, I figured it's dark out, she's got a full tummy she's drowsy. I put her on the roost,she curled up and back to sleep. Went in a little while ago to check on her and she's in the floor in the back corner all hunched down and completely lethargic. She will stand on her own, but not very long. Instead of just hunkering down like normal, she almost flops over to one side. Nothing wrong with her legs, maybe a little glassy look in her eyes, but she's been staying in the coop and it could be from dust. This just came on all of a sudden. I separated her and put her in our basement with some teramycin in her water, but she wont eat or drink. I've never had an egg bound chicken, could this be her problem? Could she be "backed up"? I couldn't tell you when she lays or how often, they just sort of do their thing and that's it lol. Oh how I hope she can be saved :-( Any info is greatly appreciated, she's my daughters "peeper". Thank you.
