Last night I did my nightly feed thing just a bit of corn. I noticed one of my marans hens was wheezing sneezing and I dare say cough. When I went out to shut off there lay light like 2 hours later I check that hen her crop had no food in it but felt like snot. I've never had a sick hen or lost one in almost 2 years I'm a bit panicked right now. Does she need medication should I bring her in the house. Any suggestions would be awseome
