We have 2 chickens that are both a year and a half old. They usually range all over our city backyard during the day. We were camping for four days so the chickens were cooped up. They pace back and forth when they stay in their coop all day. They had plenty of food and water when we returned home today and let them out. I noticed our road runner like Sicilian Buttercup staring at the back fence and standing still, unusual for her. She is not interested in eating. She looks puffed up, like she is keeping her feathers out a little. And she has not moved from a spot under the apple tree in several hours now. No coughs, sneezes, her vent seems fine (pink). Her bright red comb has a few brownish spots at the crown, sort of like a few crusty dots. Her poop has mucus. She is drinking. Our daughter would be so upset if something happened to Buttercup...any help is greatly appreciated! Thanks.
