Non-powered ventilation will be easier if the houses are shorter. A rule of
thumb I've read is a length no more than 3x width. But if you have roll-up
sides, that may be a moot point.

These were probably meant as bolt holes for a 2x12 base board, for attaching
the poly. The bottom one might also have been for bolting to a ground post.

You might also consider angle iron, with the hoops bolted to the upright
angle. I'd be afraid the 2x6 on edge would sink into the ground pretty fast,
and may provide more friction than the angle iron. if your house will be
mobile, you will probably want to beef up the cross bracing to keep the bows
from splaying.
