Hi
I have been keeping the blighters for years and found that there is never, ever, enough honey! Even on a good year!
You will find that there will be "friends" and family members that you have not seen for years suddenly appear looking for the FREE honey. Your friends friends will also need some and all your neighbours friends, friends of friends and family members too. I even had to make a donation to my daughters school as she was telling everyone that we had a shedload!
I also have an arrangement with a local health food store who is one of the very few that have offered to pay!
The truth is that the bees don't actually make that much! The weather is the deciding factor and where I stay is rains most of the time. A hive heavy with honey one day will become empty after a few days of rain and after a fortnight you will actually need to feed the bees before they starve. Lots of beekeepers lose bees, even in the summer as the bees run out of food during poor weather.
You should certainly venture into the hobby though! Its fascinating and hugely satisfying when you get it right. Expect a large initial outlay though!
