I found my 3 month old hen hiding when it was time to go in the coop and she is gasping for air. She looks fine, I can just hear a weazing when she tries to breathe. I put her on roost with her friend and she got down and stood on the floor. I now have her inside and tried to give her water but she didnt want any. She was fine when she left the coop this morning. Please help.
