Nuc beehive entrance

I made some nuc boxes for my bees out of plywood and decided to make an entrance wheel with 4 positions

There's a handle to move the wheel and the "landing board" is slightly angled down to reduce the chances of water entering the hive.

1 fully closed, for short-term transport. mainly within the apiary

3 small holes for ventilation only, to keep bees from leaving the nuc for more extended periods.

2 fully opened, it is useful when the nuc is strong, close to transferring to a full-size colony and there's a lot of nectar flow.

4 reduced entrances to help the colony defend itself better from other insects and rodents, It's supposed to block the queen from exiting the hive so it's unsuitable for unmated queens.
