Rainy day bees

I checked the MH hive last weekend. It was too cold and drizzly to go into the hive, so I kneeled outside and watched the bees going in and out. The few adventurous ones are bringing in pollen so there is brood inside. There were also about a dozen bees on the weeds/ground in front of the hive, they were cold and wet and barely moving. I tried to help the ones with their pollen sacks full into the hive, they seemed to be ok. I tried to help a few others, but one was thrown back out right away. Hopefully it will be warmer so I can swap out some honey frames to give them room to make brood com. I want to try to stop having a swarm this year.
