I had mine waaay before I had a coop. I kept them in a pvc hoop run covered with a tarp for 2 months before I had my coop ready. I had a huge rubbermaid horse trough turned on it's side with shavings in it for them to sleep in. I also had some low perches, but they prefered to pile up together in the shavings at night and used the perches during the day. As long as they are warm and protected from wind and predators they will be fine.
