This evening I noticed one of my hens was separating herself from the flock and sitting very still. Right under her beak was a swollen spot and around it near her waddles were also swollen. I checked her crop and it seemed empty not as usual because she normally eats like crazy. Feeling around a bit more i noticed two more spots as if she got stung around her crop area. Normally she doesn't like to be held but she allowed me to poke around quite a bit. She also had some mucus coming out of her nose. Help!!!! I love all my girls and need some advice.
