Hi, I am still trying to decide which way to go this winter!! We did straw last year...it is a MESS to deal with when cleaning.... Will pine bedding be enough....they have a concrete floor...how thick of a layer of bedding do they need when its sub zero outside? We do have a heat lamp in the coop to take the chill out... Also will stall dry do a good job of keeping the bedding dry in the winter? I used red lake de in the coop this summer and it seems like it turns the bedding into dust!! I am in central MN, would LOVE to hear from those of you that deal with the same temps we do. Thanks!!
