I will say this bluntly, but without trying to be mean.If you don't have the time or energy to make a chicken coop, then you aren't going to be able to have time for chickens.You have very cold and snowy winters?Your going to be spending a lot of time shoveling.Not bantams....Dominique, barred rock and Wyandotte. I have no time or energy to make my own. Need a pre-fab one!
