Okay so my Wyndytte hen has something wrong with her. She is isolating herself from the other chickens [And no they aren't picking on her] she acts really sick! i gave her some mushy laying feed, with water, and she ate it. But what should i do!??!?! Please help me!!!!! Thank you so much! Oh and days before all of this happened, she was sitting in the roost of the coop all day..
