I wasn't going to buy any but succumbed as a £30 box was on offer for £7 in the local shop. The rabbits are in a hutch/run combo down the end of the garden. They've actually dug a burrow under the hutch and live down there so am thinking they will be quite insulated from any noise?
ime rabbits have very fragile constitutions, if you can, i'd move them into a garage/shed, or if they are hiding in the burrow, could you chuck a big, thick blanket over the hutch to insulate them further?
It's hard to predict how a rabbit will react - mine freaks out if our garden hedgehog strolls up to the window, but was quite relaxed about a cat-fight in our garden this morning. She's also not fussed about fireworks and it gets very loud here on New Years Eve. Are they quite chilled out in general? I would go with lucykate's suggestions and stick a blanket over them just in case.
