I have a 6 mo. old EE. This morning she didn't want to come out of the coop. She hunkers down and puffs up with her eyes closed. She has not started laying yet. She's not eating or drinking. She was fine yesterday. She will occasionally open and close her mouth, but it doesn't seem like she is gasping for air. I don't hear any wheezing or gurgling. Her crop is a little firm and I tried to massage it, but nothing came out. Any suggestions?
