Hi Newbunny
Welcome to the BB forum. Do you have any pics of your babies to post? We’re all crazy about Lagomorphs here (bunnies).
The hutch looks cute. Have you seen those chicken/ rabbit coops with wheelbarrow-type handles and wheels? I would look for something that’s easy to relocate from grass to concrete because you don’t want your rabbit escaping like Odette mentioned. Rabbits are efficient and talented diggers!
If you’re asking if the hutch is big enough for two bunnies to live and exercise in, I’ve found that no cage or pen is sufficient for rabbits to spend all their time in. If you could give your rabbits an hour or 2 or 3 to exercise daily in a rabbit-proof space (inside is good, outside, you need to be a little more careful), that would be ideal. Rabbits get awfully bored and destructive when they don’t get their “wiggles” out, as we say in childcare. Also, you want to be careful that there are no cats or predators in your area that will scare, injure, or kill your rabbits (sorry to be so direct – I don’t want to frighten you or anything).
Do you have a plan to spay/ neuter them when their hormones kick in? For this reason, I would buy an extra pen to (temporarily) keep your bunnies separate as a backup. They can fight and this can make keeping them together permanently very difficult, especially if they injure each other in a fight. They’re young now and probably love each other to pieces, but that can all change in an instant. Just read up lots (if you haven’t already), cos we have a lot of info on the forum here. And have a backup plan.
