To add to the my wife's previous post, I would like to say that we do have a very docile set of pigs. Without piglets, they are attention seekers. As soon as we walk in the pasture, they all come running over looking for scratches or treats. I am never nervous around them. However, take a baby from its mother, and the situation is a little different. But now, we are back to normal.
Anyway, yesterday we processed another set of chickens and then got to unloading our winter bedding in the barn. We bed our cattle down with sawdust that we purchase from a local mill. They bring it in on a semi-trailer. The only problem is the unloading. If we had a skid steer loader, it would be easy. However, we only have shovels. We shovel it out of the ttrailer into a blower that blows it onto the barn floor upstairs. It is very convenient when it is done, because we will have the entire winter supply done. But, it is a lot of shovelling and since my son is only 3, his shovel is not so big to move lots at once. I do think he can shovel faster than his mother. Over the winter months, we just keep adding to the bedding pile. The fresh bedding eliminates smells and makes for some good fertilizer in the spring.
Our chickens and pigs will bed down with mulch hay. The pigs also like to sleep in the leftover silage that they don't eat.
In the spring, we spread it all on our corn fields and plow it under to make a great compost bed. Unfortunately, we never have enough manure to fertilize everything we need to.
