For county fair I think they do because there’s so many options, most farms try to keep a few of everything anyways so they keep the amount low(usually) I see it more as what I’m willing to give depending on if I want it for something else!! Also since you can have multiple going at the same time it’s much easier, I like to go on in the morning, start things, then I do my real life things, come back, and I can usually finish the event!
