(Btw that was just where they stayed until i got the coop set up. They won't stay there.)
Also, im SO surprised with how friendly they are! I sat on the ground and they were both immediately in my lap.

Depends on the breed of bantams. Bantam Cochins and bantam Brahmas can be nearly the size of a Leghorn.
To OP: You might only need to lock them in for a few days to get them to accept that the coop is home - for a couple of days, the tighter quarters should not be an issue.
Your ranging set up sounds nice for 2 birds, and they'll enjoy the 6+ hours a day with that much room. Could the chickens fly over the top? Yes, and mine have done so, but with just wire fencing it doesn't give them much to land on which discourages them from trying to get all the way over. You could consider clipping one wing if it's really needed, but I would wait and see how they behave first. If they like the set up they really will have no reason to want to escape.
As I said in an earlier post, bantam cochins aren't as small as most bantams. Cochins are a giant breed, bantam Cochins are a scaled down version. That means they are very large for 'bantam' chickens.
