Have you all seen this? Thought it was a great idea evacuating many chickens...
I heard about this on Facebook. I think that might be a bit stressful for the chickens as well. Really, if you are going to transport them, put as many as you can in dog crates with some straw, and proceed with your evacuation. Chickens will go into a sort of comatose state in the moving car anyway. They don't need to be wrapped.
