This is out first time ever raising chickens. I have a road Island Red that is raising her head very slowly from the ground and then laying it back down on the ground with her rear in the air. She is doing this over and over again. I'm not sure if she is eating and drinking and she doesn't seem as energenic as the rest of them. She is only about 2-3 months old. Does this sound like a symptoms of a disease or just weird behavior? We are considering getting rid of her in case anything spreads...PLEASE HELP!
