Hi y’all! We are new chicken owners. My husband built a chicken tractor and I had a question. The inside of the coop looks like this. We noticed they weren’t roosting so we put a temporary floor with some shavings and they huddle in a corner at night. Right now they aren’t coming out of the coop ( I’m assuming because it’s 40 degrees) and looks like the image I posted. My question is is it ok to have the bottom just exposed wire? We live in TN for weather reference. We have the wire outside of the coop as well. And will have an electric fence for night time. But is that flooring a bad idea for chickens. They are currently 8 weeks old. TIA.
