Everyone who offered advice on free sawdust to the post requesting that information, thank you. I have a horse that developed laminitis. The ground was soft, then mushy. As the horses walked big holes were made. Then the ground froze. She won't leave the barn or the concrete area next to it. I was told to use shavings to fill holes as well as dry area and also provide comfortable ground for her. I know certain wood is not good for bedding but I don't believe that would also apply to ground cover. The price of shavings is horrible. I paid 60.00 for less than 10 bags and even though the bags said expands to 5cubic ft it didn't even make a dent in the area and wasn't deep enough. I normally use paper bedding in barn and it spreads further. Unfortunately it is way more costly than pine.
