How long does it take for a new package to start building comb? I installed our bees late Saturday. The have sugar water and a pollen patty on the bottom of the hive. It's been pretty cold here at night, dropping down into the 30s. During the days it's been averaging in the low 60s. I peeked in the hive today and they were in a cluster. I see a few fly in every now and then.
