put anything over the concrete,(besides shavings)? will it get too cold in the winter in new england?..can i or should i put linolum over the concrete...also..i noticed when i wash down the concrete floor..it stays damp for quite a while...and thats with the barn doors left open to help air it out, so i'm concerned about dampness when the chickens are ready to go in there. thanks..Wendy.....p.s...or should i just have a dirt floor?..its a 8x8 barn type shed...its just resting on the concrete slabs..i think we can easily take them out from under the barn..but i'm not sure how good a dirt floor is for new england?.....thanks
