We initially had a 10 x 10 chain link dog kennel and bought one of those pipe roofs with tarp cover that the hens could go in but the first winter the tarp tore and now each winter we put on a new industrial tarp to keep it covered as well as a support beam in the middle of the kennel. We have also put tarps all around so it's protected in winter. In summer we roll up the tarps to let fresh air blow through. Inside is a hen house, a rack of hen nest boxes, storage for chicken stuff and a huge parrot cage. In winter I put hay on the floor and bed it deep. It works well and isn't too messy to clean come spring.
