My 10 week old EE chicken has been acting different for about a week now. While the rest are running about the yard together, she stands still alot with her eyes shut most of the time. She also sleeps standing up. Is that normal? Even on the perch she is standing a lot instead of sitting down. When I brought them all out to the yard this morning one at a time, they felt warm and were happy to see the yard and ran off singing. Her feet felt cold and I put her down where she just stood still again. The others are never sleepy during the day. They rest together under a tree once in a while, but for the most part are busy all day. I thought maybe it was the heat, but I don't think it is THAT hot. Plus, all the others are not phased by the heat. I also bought grit thinking she wasn't getting enough from the yard. She ate some, but still just standing. Also, I have her water with electrolytes and yogurt. Running out of ideas. Anyone else go through this? Thanks so much in advance for any input!
