This applies to both coop and/or run:
Here's a great description of contents and how to manage organic 'bedding' in a run or coop...and there's a great video of what it looks like.

This is how I do my run(I like dry...
I had planned to have the main run with 3-4 pop doors off the north side and use portable electric poultry netting to define rotating 'pasture' areas in the field beyond.
Didn't happen, mainly because of high hawk population here and some other circumstances.
True Dat...any livestock really.
I knock snow off from underneath my 14ga 2x4 mesh run roof with the snow shovel,
if it doesn't fall thru.
Ditto hat/hood and coat zipped up tight to neck.
And I keep a path shoveled all the way thru the middle, throwing most of it thru the run walls. Helps for access to keep roof clear, place...
That was an exaggerated guesstimate...but it was a lot.
Not sure what to recommend, covering large areas difficult in snow country.
Sounds like Ralphie has a viable setup.
Welcome out of the BYC 'closet'!
Might take them 2 weeks... ;) ..depends on what's growing there.
Sorry.
Tho that fits the '10sqft per bird in run' 'rule of thumb',
that number is a bare minimum for avoiding crowing and behavioral issues.
Has nothing to do with vegetation...there really is no...
