My daughter works at a little shop that sells organic stuff. They keep a flock of about 20 laying hens out back of the store to sell their organic eggs. She just brought me one of the hens that is gasping for air. They didn't know what to do. I've examined her. She looks to be an adult Barred Rock. Her crop appears empty. There is no discharge from nose or eyes. I cannot feel anything abnormal along her throat so I don't think she has anything caught in there. She seems calm and quite normal except to breathe she must extend her neck, open her mouth and pull in air, making a wheezy noise. Her comb is red, so for now she's getting enough oxygen. I've put her in isolation and just watching her. I will check for gape worms in a bit. Another odd symptom is she has made absolutely no sound except for the wheeze when she breathes... no cluck, no squawk, no nothing. Any ideas? Thanks for any help!!!
