Happy Beekeeping!!! I hope your hives are all doing well. Your bees should have started raising some brood and gathering pollen. As usual, Texas is experiencing its crazy weather. These cold and warm weather spells can be hard on your hives and result in starvation. Now is the time of year to build, repair equipment, and order queens and Nucs. Many suppliers sell out very early.
If you don't like the weather in Texas just wait five minutes. It'll change. We've had some great weather lately but it is turning into a nasty winter storm. Some tips that can help your hives survive these intense cold spells is; moving them closer to each other (to share heat), or at the very least set up some sort of wind block to shelter them. Make sure screened bottom boards are closed off and entrances reducers are in place. If your hives are really strong and well fed you should not have too much to be worried about, but it never hurts to be cautious!
