We have three 2 week old chicks, and one, the Ameraucana has diarrhea. She is drinking and eating well, and seems to be okay, except for when she sometimes goes to lay down she kind of falls over on her side. She seems to be alert and happy when she is not sleeping, so I do not know if I should be concerned. The other two chicks are fine and showing no similar symptoms. Is there anything I should do for her?
