oooh any reason?? I hope you don't have any wild animals there who might harm them in any way.....
Yes there are foxes around - so maybe there was a fox prowling. The bunnies are in a solid enclosure - nothing can get in, they can't get out. It's locked and double-checked every night. Plus they are inside their double decker hutch in the night. But yes, a fox might have unsettled them, but they are perfectly safe. Neighbours didn't complain
Your Queen retiring did make our news as well.
