Hi. I have a flock of 6 chickens I got last spring. This is my first time with chickens, so there is a lot I don't know. Yesterday, I noticed my golden sex link pullet had her feathers all fluffed out. I thought it was strange but didn't worry too much. Today she is the same. She just stands around and isn't interested in eating or drinking. I've been doing all sorts of research trying to figure out how to help her. She is one of my best layers, but hasn't laid in 2 days. I checked to see if she was egg bound, but didn't feel anything. I checked for lice/mites and she seems fine there too. She's not coughing or wheezing. Her comb is still red and she doesn't have any discharge from her eyes. I haven't seen her leave any dropping since I separated her from the flock and put her in an animal crate inside. But I didn't notice any crazy looking droppings out in the coop or run area. I'm feeling way out of my league here.
