Friday, 3 week old chick was fine, Saturday morning couldn't lift her neck much, not moving around either. (Still managed to get to the water and food.) Started her on electrolytes/vitamins and by now she's better /can lift her head/ moving around fine, still eating and drinking, but every so often she'll have an episode where she tucks her head and runs backwards. Almost looks like a spasm. She hadn't been doing that much today, but when my husband gave them their egg treat, she did it maybe 4-5 times in a short time span.
