How do you exercise your bunnies?

[Hopstheduck]

I rehomed three mini lops yesterday. I did have a rabbit years and years ago, but it's been a while.

The girls are currently living in a two story 4 x 2 hutch (from their previous owner), and have a separate 6 x 4 run. I feel they are a bit over crowded and I am worried about foxes. I have ordered them a new hutch, 7 x 3, this

I was hoping they could have the run of the patio during, but one immediately jumped a three foot wall onto a border so no chance there! I've now put them in the run, but it seems so small! What do other rabbit owners do? I was intending to secure the fence, but one side is in pretty bad condition, and the neighbours own a terrier, so not sure it would work!

Your link doesn't work.

I bought 2 large runs, both 6ft x 3ft, eacj with doors on the side.

I open the doors and push them together to make one very large run which sits on the patio so they can't dig out.

When I'm at home they have the run of the garden. 6ft fences all round the garden with bricks along the foot of the fences to prevent burrowing. Local cats are scared and leave them alone.
