Re: Queen rearing equipment
I have the Nicot system here, which is very similar to the Jenter system. Yes, it is a plastic box you put the queen in so she lays in plastic cells that have the cup behind the cells that she is actually laying into. When the eggs become larva, you remove the cups and put on a cell bar and put into a cell starter or cell builder for the bees to draw out into queen cells.
I've been keeping a few hives for the past 20-25 years, and no longer treatment free as I got tired of the losses.
