I have learned in the few years I have kelp bee's that if you know how to understand bee's, beekeeping just needs a little understanding and common sense (experience come with time ;) ). A few ask the question all the time like I want to split a hive in the early spring when can I do this, well the answer is in your hives, all you have to look for is drones, odds are if your hives have drone the local hives will also! you dont want the bee's to raise a queen until she can be successfully mated. Or when you want to do a spilt and can't find the queen, well that is easy just make sure both sides has a frame of egg and larva, honey , pollen and they should do fine or if you want to add a queen to a split, well the day before your queen arrives split the hive the day before and just go back to the hives 2-4 hours later and the load split will be the queenless hive. Or when new beeks inspect a hive and see no larva or eggs they think they are queenless, all you have to do is ask the hive if they are,, and what do I mean by that? well put a frame of eggs and young larva from another hive in that hive and inspect that frame in a few days, if they are queenless then they will start building queen cells and they aren't building queen cells then they probably have a young queen that hasn't started laying yet or check the frames for laying workers (multiple eggs in a cell). a lot of time a new beek will see no larva and think they are queenless and go and order a queen only to install her and have her killed by the hive because there is already a young queen in the hive that hasn't started laying yet, then they are out the price of queen and shipping. another thing is when you do a removal, with some experience you can tell if the bee's have been there awhile or not because old dark brittle comb is a sign of years and if that hive was lose and a swarm replaced it you could probably see were they repaired wax moth damage, just takes looking at comb and seeing the difference it changes every year... that's just a few to start with, lets see how many we can get, got to go I will add a few more later!!!!! Just a few things I thought I would throw out there. some may not agree with some of the thing I said above but these have worked for me many times...... if you have any good ways to understand what a hive can tell you add them please!!!!!!!
