We purchased our property last year, and I finally have the room for chickens - so this will be my first time constructing (or rather, converting) suitable living conditions for chickens. We have a 16x18 barn on the property that I will be converting for chickens. I have done tons and tons of reading, and somehow I still have about a bazillion questions, so I figured it'd be about time to start a topic and get some help. 
I live in Northern Ontario, so it gets pretty darn cold up here. Figured that's probably information that might help.
First question: Flooring. Currently the barn has a plywood floor and I thought I'd cover it with some vinyl flooring for easier cleaning..... until I went to Home Depot and found out it'll cost me at least $2/sqft and that adds up VERY fast for a barn that's 16x18 (approx 290sqft) - and I am not willing to spend that much. I don't care too much about the plywood degrading over time as we'll be tearing this barn down in a few years anyway. Should I just stay with the plywood? It's not nearly as easy to clean, though.
That leads me to question #2 that's related; floor litter? I can't seem to decide between sand or a deep litter method. I like the idea of sand more, but I think it might not be the warmest option in winter. I don't mind the deep litter method either, however I read it's mostly effective with a dirt floor, which I don't have. And I would really like to use poop boards, wouldn't those defeat the purpose of deep litter? What would you guys do? Any other options?
Then Question number #3 - There is a covered area right next to the barn that'll be perfect to convert to a run - but I am not sure if it'll be big enough. It's about 7ft by 18ft. Would this be big enough for about 16 chickens? (I am picking up 16 chicks at the beginning of April) Do I make the entire run out of hardware cloth? It seems very expensive to do a large part with hardware cloth. I just picked up 2 rolls for $16 each (24" by 5 ft - 1/4th inch) we have LOTS of predators around. (Lynx, bears, wolves, coyotes, and I'm sure a whole host of the smaller predators, too - I've never seen any of the larger ones but the tracks in the snow and pictures from neighbors have me convinced! )
I am sure I will come up with dozens more questions, but I think these are my current main ones. I have attached some pictures of the barn (still a mess inside, cleaning out and disassembling the mess the previous owners left behind!)
Thanks so much for any and all help! Trying to get it all done as well as I can!
