ange, I have been tossing down pine shavings in my large chicken yard every since it started raining here. It keeps the chickens up out of the mud by absorbing the water & letting water settle below, fills in low areas that they've dug up, keeps the yard without smell (my friends comment: it doesn't smell like a lot of chicken yards do that I've seen) & I can hardly wait to shovel it all out in/after Spring (when things are dryer) to put this Winter/Spring aged compost into the garden. I also use fresh pine shavings in my nest boxes (as I have a few young chickens that like to sleep in or nearly in the nest boxes to leave me droppings to clean out in the mornings which is easier with pine shavings) & coop (straw & grasses mold easier than the pine shavings). It's a good deal for all. They sell it in large plastic bags/bales at the livestock feed stores & it's not too expensive for the quantity you get. The only time I don't use it, is for any of my brooding chicks; then I use cut straw (cut with my sizzors) it is an eddible bedding (not like pine shavings) & I just change it often as you would with any brooder bedding for chicks. Best wishes in finding what works for you!
ChickieBooBoo, can I assume that a bale house is made of bales of straw or the like? If so then maybe stack it higher & put a roost inbetween an upper stack of bales so they will have the higher roosting height that they will like & feel safer at. Let me know if I'm way off on what a bale house is. My husband & I both have parrents from Canada & have heard the stories about how cold it gets there, along with how beautiful it is.
On a funny note: We once knew some people that had a lot of garden & livestock chores, living on a mountain top. So when they were approached by a well mannered/gentle fellow that liked to "live off of the land" who offered to do chores in exchange for living on their place, eating from the garden, chicken eggs, feed grains & goat's milk, & with no shelter required, they took him up on the offer with much success. One day when we visited in the winter, we saw some guy comming out of a large pile of straw pulling straw out of his hair & happily chomping on some green sprigs (maybe parsley); it was odd & surprising. In looking around it was evident that he was a very productive, consistant, attentive guy who took care of everything very well & took being a "naturalist" to a well working extreme. Although he did not like hanging around people & had very little to say, you had to admire him & his odd ways. It's so fun to meet people that delightfully surprise you.
