Noodles, my 2-year old golden buff hen started acting lethargic yesterday. She stayed in the coop most of the day, and only ate a little. (I did see her eat and drink yesterday.) Today, she was still acting strange. When I picked her up, she hardly reacted. Then when I put her back down, she wobbled as if she was dizzy. I called a vet who told me to watch her -- and if she was still acting strange tomorrow, to bring her in. I gave her some water with a syringe earlier, then placed her in a nest so she could sleep. I just went down there and her little head was down, tucked under her wing. I picked her up and she was gone. Still warm, so it must have just happened. I'm heart-broken. And I'm feeling really guilty. What could have happened to her so quickly? Earlier this week, so was just fine. There was no physical signs of anything wrong. Should I have just brought her in to the vet today, instead of calling? He didn't seem alarmed. Could he have helped? Should I be worried about the rest of my flock?
