Mine is too varied,, sometimes like after a big storm, I cut every day, then sometimes like during mowing season I won't touch a saw for weeks, but I might get to splitting and stacking in the late evenings then. It also depends on other chores, plus how the ole bod is feeling, I won't cut if I am dicey with the back that day.
I guess it really varies between the guys who cut pro and not. Even pro on the side you need to spend a lot of time at it, just cutting your own wood and like doing the farm cleanup here...too big of a variable. In mud season/winter I usually do a couple days felling and some bucking here and there, but I don't haul anything out until the ground firms up. I wind up doing most of my cutting during the time a lot of guys here hang up the saws, heat of summer when the ground is hard, just because I need that access.
I *could* do it more, but not much of a firewood market around here, there's already like dozens of part timers selling wood all over and prices are ridiculous low, IMO. I counted on the way into town the other day, there's two different roads, on the one larger road, 4 different firewood for sale guys working right off their yards facing the street, then in town, three more I can think of readily.
I would say in my area it is predominately propane heat.
As to prices, an example, one guy I met the other day sells a full size pickup bed load, stacked to top of the cab for 65 bucks, hickory. He's a roofer with no work right now. Multiply that by any number of other guys doing it, just to have some money coming in. It's a buyers market, not a sellers market for sure.
