Last night one of my Button females was acting strange. She was sitting in the center of the cage fluffed up and getting knocked over by the others. I took her out and she didn't fight me like normal, she just sat there and didn't move at all. I gave her a few drops of a Nutrical adn sugar water solution for a boost. She perked up a little bit about an hour later, but when I checked this morning she was gone. She was my only black hen and I'd grown a bit attached to her. All of the others are acting fine and eating well. This one just never seemed to eat.
