I brought home this little guy today and at first I figured that he was stressed out from being hatched and then shipped right away. The other 3 I also bought are up and running around but this little guy just sits there. He will eat and drink and stand up as long as a stand him up. Once hes standing hes good for a little bit then looses his balance and falls over like a tiny drunk. His legs seem fine, no curly toes or anything like that. He just acts exhausted. I finally separated him from the other chicks because they all dog pile on him and he cant get up. Any ideas?
