Hey guys, we have one coop for the laying hens, its not big enough to add 3 bantam cochins plus avoid the pecking of the big girls. The hutch we ...ahem, DH built for the meat birds this spring is what is being constructed as a bantam house. So now it is a 4'x8' floor. Today (bless him) began remodeling, building a "coop" in 1/3 (or one of the "doors") in it. He has insulated it on 3 sides with styrophom between two sheets of plywood/particle wood, with a chick door 6" off the floor that will have plexiglass door to allow light in, and the front door will also have plexiglass window to allow light in. Because I use the deep litter method in the Maine cold winter, no insulation on floor. Now, for 3 Bantam Cochins, is this going to be warm enough through our endless fridged winters? Lets say no heat or any outside source except sun (if anything like last winter, we didn't have that either). The remainder of the hutch will be plexiglassed in to stop drafts and they will have the ability to go in and out of the coop. Please share your opinions or concerned. We'll be grateful, Thanks!
