Hi everyone, I hope someone can help me. I just got a hen and she is about 3 months old. She was running around, eating, drinking and just being a fun chick. The other day I went outside to feed her and she was just standing there and not running away. The next day she was just sitting down and had a hard time walking. Now she does'nt walk at all. She eats and drinks and is very alert. Does anyone think she is sick or just injured?
