I am a new beekeeper of two years and thought I would experiment with a modified warre. I got a package of bees, installed the queen, gave them a pollen patty and sugar water mixed with honey b healthy. I then left them alone. On day 6 I went to check on them and noticed bees coming and going but with no pollen. My other hives had a lot of pollen traffic. The next day (day 7) I opened the hive to find the only bees there were a few dead ones from the package. There was only a little drawn comb and it looked like they had not really touched the pollen patty. What happened? Did they swarm? Why would they if they had plenty of room and food and water? I live in Oregon and it has been very rainy and cold until day 6 and 7 when it hit high 70s. Thoughts?
