This is why I advise against april packages in the north east.
Right now their is a truck load of Packages headed to CT for delivery tomorrow. After weeks of above normal temps and plenty of sun, people are anxious to get bees. Tonight the temps are predicted to dip and a snow storm is moving in. Looks like they will be all right as the weather is predicted to warm back up by the beginning of the week. They may have to wait until Monday to start hiving. Hope for the best.
Always question Conventional Wisdom.
