Hen was fine yesterday, laying eggs all week. Today, she is acting zombie like. She normally is flighty and does not like to be handled. Today she goes to the food and looks at it. She picked up a couple pieces and dropped them. Crop is empty. She's a 7-8 month old dark brahma bantam. I picked her up easily and she snuggled in my arms and just laid there relaxed and seemed to like the attention. So zombie like, not eating, crop full, I check to see if egg bound, can't feel anything. Any ideas?
