I know it's been asked a thousand times and that there is no precise answer for every animal, but I'm looking at getting 2 LaManchas for milking and am trying to figure out how much straw and hay storage to build into the goat barn. I'd like to keep at least 3 or 4 months worth on hand if possible, so on average how much hay and straw will those 2 goats go through in a month. Thanks
