Man I am confused now. I was goin to put my chickens out at about 4 weeks in a large pen outside fenced in (top and bottom) and then put up a large tent like for them, What it is is a canopy that you can buy almost anywhere that has the metal poles. I was goin to take the poles off and just sit the top on the ground so they would have shelter. But I read they cant have drafts at night? So this wouldnt work? Their coop has to be enclosed? I didnt want to do anything permanent since they wont be here long. What do you use?
