When cows lay down does it mean it's going to rain?

Weather folklore dictates that cows lie down when it’s about to rain, but the Farmer’s Almanac says this has not been proven to be accurate. Cows tend to lie down in a field when they chew their cud. Other myths include: jazz or lowbrow music encourages better milk production, the birthing or weaning of cattle during the waning of the moon predicts poor breeders, running away can be prevented if a piece of a cow’s tail is cut off, and feeding a cow her own hairs will make her forget her previous owners.
