A frame, - dont have one, wouldnt want one. For one thing, the snow fall has been tremendous this year and we have piles and drifts over 4ft tall, not exagerating! It seems you really want to utilize the tote and move free grazing method. Consider a permanent dwelling or coop for the colder months and build an A frame to suit your purpose in the spring and summer. And yes, by all means, build the coop near or by the house so you can get out to it through the heavy snowfall!
