It's COLD out tonight! And WINDY! My 6 (6 month old) chickens are in the hen house for the night, but as of right now it's not draft proof. My husband made the house with the back (east facing) wall and floor made out of plywood and the rest was made out of recycled pallets. There are spaces about 1/4" in between these sections of wood. We are planning on covering the inside walls with plywood, but the cold came upon us suddenly. My chickies must be pretty cold tonight. Are they going to be ok? Here's a pic of the hen house (the nesting box isn't in the pic). The windows are now covered with plexi glass.
