It’s mostly fairs, for a lot of which it’s required for the birds to be there every day the show operates- often longer than 5 days, between 5-7 for most from what I recall, and early removal for a few resulted in immediate disqualification from any rewards.
All of the shows I’ve considered attending/have attended have also been over a 1.5 hr drive from my house, so doing anything longer than 2-3 days isn’t manageable for me, between the regular care the birds would need, general anxiety about leaving them there so long, the long drive it’d require, and fact i’d have college to worry about too.
I agree that if it was something big like Ohio, it’d be something I’d be more willing to commit to, but those shows aren’t nearly as big as Ohio.
