Re: splitting....too soon?
You also have to do some bee math. If you figure a growing colony can double the amount of capped brood in 3 weeks, you might decide to wait a few weeks.
If you have 4 frames of brood and make a split, each half ends up with 2 frames of brood. 3 weeks later, you have 4 frames of brood in each half, 6 weeks 8 frames.
If you wait to do the split 3 more weeks until they have 8 frames of brood, you can make a much stronger split of 3 frames of brood and leave 5 with the parent colony, in 3 weeks you have 10 and 6 (instead of 4 and 4).....that's 3 weeks well spent.
The irony is free. It's the sarcasm you are paying for....ironically.
