About an hour ago one of my hens was not walking and would not eat or drink anything .. her feathers are all ruffled and she was just slowing moving and seemed out of it. Also her poop was pure white and clear liquid. I ran to get some Corid to treat her and when I came back she was out walking around free ranging with the rest of the girls. My question is should I still treat them or wait and see how she does through the night and into tomorrow? She still isn't 100% her normal self but she's back up eating. What the heck!?
