Should I put anything down to protect plywood floor inside the coop?

I am a relatively new chicken owner. I upgraded to a bigger and better coop and before I move them in, I was wondering if I should put something down on the plywood floor to protect it or should it be fine as is? I was thinking about peel and stick tile but we do have extreme temperature swings so I feel like that might be a bad idea. I plan to layer up pine shavings and use the deep litter method for the winter. Just hoping some experienced chicken keepers can help me out here!
