Our busiest times are spring and late fall. Spring has so many things all happening at once. We're fixing fence, building new fence almost every year, pigs are farrowing on pasture so we;re constantly moving them in portable pens to fresh pasture daily. Cows start calving 3rd week of May and pretty much take care of themselves, but we check once a day, and since they're usually at least a mile from home it takes a bit of time. I usually try to check them at dawn, then start my day with all the other stuff.
Fall always seems like I'm trying to do all the things I wanted to get done all summer. We put bales out for bale grazing and pull twines off while the weather is good, so that they are ready at any time if we need to feed the cows, otherwise the cows graze stockpiled pasture most of the winter. But there's always firewood to stack, straw to haul in, feed to bring in from neighbours for the pigs, etc, etc, etc.
And of course, we do all of our butchering for direct marketing in the fall. Grass finished 2yr old beeves and pastured pigs all go to slaughter from Sept. 1st until about mid-October. We deliver most of the meat to people's doors so it's hectic trying to coordinate all that with city folks.
