I got my bees on Sunday and put them in their brand new hive. They are still happily buzzing around. I have not opened the hive space as a beekeeper friend told me to stop bugging them or they'd abscond and find my hive inhospitable. However, since the bottom has wire mesh I am able to look in that way and I see that they haven't built any comb. This concerns me.
How long after installing bees should I expect to see comb?
Aside from making sure they have sugar water, is there anything I should be doing?
