It works for me and I find in a poor temperature spring, (oil seed rape is early here in May), I can leave what OSR honey there is for them to take back down if they want it after swarming, (also takes place in late April - early May). In a hot Spring I would have taken some of the OSR.
I haven't taken my "share" this year yet but I have hives that swarmed in May with about 35kg on them at present - that's over 75lbs I think you will find - more than enough with my hives to give me a few Euro even after paying the State a bit and without screwing around constantly with the bees that are in my care.
I hive brood boxes that haven't had frames removed for years on end and are in constant occupation with strong colonies that follow one after another......
......but, of course this is France and although I envy the prices you get for your honey, I'm oh so happy I don't have all the problems and issues you appear to have over there, talk about making life hard.
On the subject of prices, I get about €6 a kilo retail, or about €2.50 / €3 wholesale if I wanted to go that route. That's about £3.25 retail a lb. for quality, clean, no chemical honey.
So, according to the great ones on here, I'm not a bee-keeper BUT I am someone that provides and cares for them in a stress free manner.
