In going to Be ordering sad any day now, one last question!! I have two coops, one is an extension to my pole barn , 16 by 27 or so and the other 12 x 16 or so, the larger has concrete floor and the smaller is a converted shed with painted wood flooring. When using sand as bedding does flooring matter?? My husband said the sand will not be good in the ine with wood flooring ( but he likes to pretend he knows things), and my uncle said the concrete flooring would need insulation of some sort before the sand is layed down. I do live in Michigan so we get into 90s in summer and just below 0 for part of the winter.. Isay they are both being over cautious.. What do you guys think?
