Rabbit hutches need to be well protected from rain, snow, wind. In winter, extra hay should be provided. Bunnies should have a house in the hutch for protection against the elements. The top of the hutch must have a secure covering. When severe storms or temperature drops are predicted, it's best to bring the bunnies indoors and keep them in a cool room. If the weather is not fit for humans to be outdoors, it's definitely not right for the bunnies.
