Unless she was blocking 'em up with concrete the poor little rabbits would just dig back in. Mummy rabbits put their babies in short tunnels called 'stops' and block them in all day to go out grazing, then unblocks each time she visits to feed. Sometimes she will split her litter across several stops.
A thought that occurred watching the Rick Stein clip - why did they load up the cider press without press cloths? Is that what made the actual owner raise an eyebrow?
I've only ever seen hessian/jute sacking used, I believe other materials (muslin etc) are used but its normal to layer sacking, straw, apple mush, over and over folding in the loose edges of the cloth to hold the 'cheese' together. Otherwise when you increase the pressure, it will all splurge out the sides!
Also drinking more than a few sips of that pure, raw apple juice will give you the gut rot and trots like you would not believe - ask me how I know unwise child.
The more I see/read the more I think these two know the bare minimum about farming, cider making, re-wilding etc, they're just bullshitting on a grand scale. I wonder if the scale of the french property scared the shit out of them and they ran away from it.
