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.
The more that is in direct sunlight the more hay that will get that first 30% drydown through the leaves. Do not be in a rush to rake the hay. Again the hay that is in direct sunlight the moisture in the stems will heat and the resulting vapor pressure will drive out the next 40% maybe 50% of the starting moisture.
