i just put my bees in today and the weather forect says 34 degrees tonight do you think they will be ok or is there something i should do?
If you mean that you installed a package, they will be fine. A package has no brood to keep warm. If you installed a nuc in a new box, they should be fine as well. You just don't want to add too many empty frames to the brood nest in cold weather because that could result in chill brood.
An entrance reducer will help slow heat loss.But,yeah they will be fine. We did it before followed buy a week in the low 20s.
