My chicken Moa, an eight month old Black Star chicken recently started limping. Two days ago, she started limping and I first noticed this when I opened their coop in the morning. I thought, this was probably not a large problem, because she was barely limping. I thought I would wait until the next morning, to see if she got any worse. She did she continued limping, not too much worse, but not better either. Now, she is walking around like she's incredibly dizzy. And she only takes short steps before she sits down again. She is eating and drinking. Could this be a stroke? What do I do?
