When to move a house bun outside permanently

[susiemae]

I know its still too cold at night at the moment, but whens the best time/minimum temperature in everyones opinion for house buns to be moved outside permanently. Domino and Cookie are out all day but come inside at night at the moment. They have a lovely playhouse and run that they can move into permanently when the weathers mild enough:D

I think when there is no more frost and you find a good temp at night which lasts,maybe beginning of spring.
