The venom of the black widow spider contains poisonous chemicals that make people sick. Black widows are found throughout the United States, mostly in the South and West. They are usually found in barns, sheds, stone walls, fences, woodpiles, porch furniture, and other outdoor structures.
Some types of grass hay, in dry weather conditions or on dry ground, will be much too dry when baled as small bales using the eight to 15 percent moisture (the traditional rule of thumb) as a guide. Some of this grass hay produces the best quality bales when baled at 24 to 30 percent moisture.
How much storage area is required for hay? Baled hay requires approximately 250 cubic feet of storage space per ton of hay. An 1,100-pound horse eating 1.5 percent to 2.0 percent of its body weight per day in hay would eat 16.5 to 22.0 pounds per day, or in one year about 3 to 4 tons (100-120 bales of hay). Four tons of hay require 1,000 cubic feet of space or a storage area roughly 9 feet high and 11 feet x 11 feet (9' x 11' x 11'). In other words, a horse fed hay all year would require roughly an area the size of a box stall to store one year's supply of hay.
