I've long read about how some choose to clean the barns fairly regularly in the winter, and others like to let the manure pack build up to provide "warmth" in the barn. My first year, we had such long intense cold periods that the manure pack seemed to me to be frozen. And it was a heck of a job to clean out in the Spring. So this winter, we cleaned every one to two weeks. Kept it raked in the intervals. After this last storm, we could not get the barn door open. After a day or so we liberated the smaller girls and the bucks from their confinement up on the hill. But the lower barn was snowed shut with three feet of snow and we had to climb over the door to get in and care for them. After a week, the place began to smell. So we did the only thing we could do, which was to spread 2 bags of feed grade lime and a bale of pine chips over the floor. It worked well on the smell! But the other day, I was taking out a large round plastic tub we use to feed the Nigies their hay. They like to sleep in it if their is hay left at bedtime, and I always feel and look to see if they have peed or pooped in there before tossing that hay. And it was as warm as a heating pad at the bottom of the tub. I put my hand on the pack under the tub (remember, they cover everything with hay so there is little or no poop or pee on top) and it was so warm it made me nervous!!! It felt like a heating pad! Right there where the weight of the tub with girls in it had pressed on the hay, there was a lot of moisture too, but no wetness from kneeling elsewhere in the barn. So, now I don't know what to think about this!
