Buns in runs on what use to be grass over winter or not?

My 2 hutches of bunnies both have attached runs, which did have grass in the runs until the last lot of rain and basically has turned to mud.

I'm thinking of putting paving stones in the runs for the winter then lift them up in the spring and lay turf. It's just the buns seem to have to constantly be hopping through the mud in the runs and I'm concerned that it can't be doing there paws any good being in mud lots. I know in the wild the bunnies live on grass but they aren't constantly using the same bit. Does this seem a sensible idea?

Thanks

I would put paving slabs down. It will just get more muddy as winter draws in, and standing in mud is not good for their feet at all.

You could put a clear plastic roof on the run and then it won't be so muddy

Although if want them to be on grass, it would be a good idea to place turf over some mesh to make sure the bunnies can't dig out and predators can't dig in. :wave:

If it were me, I would lay paving slabs. The main run for my rabbits is on paving slabs, with access to an area of garden for running and digging.
