Hi, my one of my pullets is not eating, or i have not see her eat. She seen depressed. She drinks for sure. But she is very sluggish, and always lieing down and when she is awake and up she barley walk and when she does she is very trippy. Kinda like she drunk or something. She holds her wings out to the side a little to walk better. She refuses to leave the coop! So what wrong with her and what can i do to help her?
