My three wethers have straw bed about 10" deep in the shed and have done well with nights in the single digits and cold wind chills below zero. The get hay and a bit of goat pellets each day.
You know, you might want to give some thought to just stuffing it full of insulation, old rags, towels - something that will block the winter wind, but is removable next summer when it gets hot....so I am going to use some crack filler spray in stuff there.
What does your little guy think of the chicken? That has to be comical at times. Yeah, I hear you on burning stuff. Our burn pile has become a monster that we are still trying to figure out what to do with. There are a couple of very tall cottonwood trees that are partially dead in the middle of it, and lighting it up could get very dicey very quickly.Will do. One of my chickens (I have at least 3 dozen) decides to keep him company every day. This buff Orpington pullet keeps hopping over the gate and picking at his hay, though none of the others go in there with her.
Tomorrow my husband will be home, and we have some items to stow away (like my 400lb gorilla, I mean tiller, that is sitting out in the garden from where I finished turning under manure and such a couple weeks ago). Our garden has a short fence around it, so I can take him out there and let him poke around some. He spent some time out there with us this last week when we were doing a burn pile after the last round of snow (moisture on the ground, no wind=perfect burning weather).
