Is it ok to put guinea pigs hutch back outside yet?

[LouMacca]

Guinea pigs hutch is currently in the childrens playhouse. I do put them out in a mini hutch with a run when the weather is fine.

Is it ok to put the hutch back in the garden yet or is it still too cold for them at night? Thanks.

It is too cold - there was frost on the cars yesterday morning - I'm in the south. I would wait until May as sudden changes in temperature are very bad for them. They come from a warm climate orginally.

Thanks for advice. It has gone really cold here again and is very vet (typical Manchester!) Will wait until the nights are milder, I just feel really mean that they aren't able to run around as much.
