Dave, you’re doing a great job. Thank you.
Great Video
Glad you enjoyed it!
I need that hat dude!!! I love it!
Hi David
I have 5 hives in NH and have problem with one hive now
They survived the winter strong I started feeding them in march and now one hive is dying out Fast bees are dropping to the bottom board
I removed the queen 2 weeks ago and gave them plenty of food and brood from different hive with eggs and was praying they will make a queen but no luck and now They are down to 4 frames of bees
I removed the queen because of chukbrood
I find bees dying in the cells
And they have lots of food,
I checked for mits and don’t have any
Any help I would appreciate it
Thanks
Wait for awhile. It will get better or it will get worse but you have to give them some time. It takes a month to get a new laying queen this way and then they need to start building up.
Letting bees raise their own queen is risky.
good work
Paul can you comment on remedies for chalkbrood, which seems to be cropping up out here after a wet and cold spring. I was always taught to do a shook swarm for a really bad case, and also now I read that one remedy, although unapproved for use, is the use of thymol-containing products (which are approved as miticides). And I suppose a little TLC (feed, close quarters) helps?
HI WW
We rarely see chalk brood so I don't have any great insights. We are careful about picking breeder colonies ( no chalkbrood) and make up splits at the time bees would swarm. Early splits or colonies without enough bees for brood could lead to poor care of the brood. That's all stuff you know already!
Forcing a brood break or replacing the queen will remedy chalk brood.
Wow I was scared a little bit. Good Job.
The tipping the hive one.
Maybe I should have qualified this one 'don't try this at home' It works for us here but don't try it if you feel unsafe.
I believe I have a hive that has chalk brood now, and its fall, is there anything to help them or do you just hope they take care of it,
Chalkbrood is a stress disease and some bees are more susceptible. A strong colony and good weather are ideal but you can't always do something about the former and you aren't in charge of the latter. ;) Ideally you'd requeen it next spring.
and hope it makes the winter
well you say stress like maybe robbing? I believe they had robbing going on and that might have done it, I'm going to check it this weekend and hope things are getting better
why are supercedure cells on the surface of the frame and what is the difference between those queen cells and the ones on the bottom of frames
Thanks!
Hi Mel
No difference - they are all supercedure cells.
Thanks!!
What is the key factor in determining you have a failed/missing queen and the stage of laying worker? In this video, was a determined effort made to make sure the queen is no longer present?
Hi Bruce
This video was filmed awhile ago so I don't recall the exact circumstance. It's often hard to determine exactly what's going on in these situations. We make our decisions based on our best guess. How's that for science from a University!
Could a fully mated queen be introduced, rather than a queen cell?
Hi John
Yes it could. When this video was filmed that's what we had available. Queen cells are a bit more readily accepted in conditions like this though.
Ok, I'll take the bait.... how do you tell a queen is laying a drone egg in worker's cell? The statement was made at 1:22 of this video.
Hi Bill
Thanks for asking for the clarification. When a queen starts to run out of semen she lays a few unfertilized eggs along with many fertilized eggs. Kind of like an engine misfiring. As time goes on she lays a higher percentage of unfertilized eggs. You can't see the difference between fertilized and unfertilized eggs but you can see that the cappings on pupae reared from unfertilized eggs in worker sized cells bulge out just like they do in drone sized cells. At 1:22 by 'just starting' Dave meant that only a few cells showed this sign.
Ok, Dave mean the appearances of the cell (cappings) not the appearance of eggs laid. Boy, Dave sure had me scratching my head, cause for all my years keeping bees, I still can't tell one eggs from another. Thanks for answering my question.
You are welcome Bill
How old was the queen in this hive?
Question 1: If an unfertilized egg is laid in a cell for a worker bee (smaller cell), will the drone develop to maturity, or end up dying?
Questin 2: If the drone survives to maturity, will it be smaller because of the smaller cell, or will it enlarge or expand the cell that it grew in?
Question 3: If the cell gets enlarged, will the bees repair it later (make it the right size), or will they use it again even though enlarged?
These are problems that I may never run into, but I am curious about it anyway.
Thank in advance to any that answere.
Hi TK
Good questions that I can actually answer!
1. yes he will develop to maturity
2. the drone stays small but is still capable of mating
3. The cell diameter remains unchanged. The cell depth is extended for the drone and then pared back down to worker depth.

Thank you so much.
Doesn't seem to be enough info on chalkbrood anywhere? I would think there wood be. People talk about requeening and I find that approach only works for those that don't have hygienic bees.
However when you do have hygienic bees there is no info on it. I would think it's a serious disease and yet nobody seems to take it seriously? Although this is a good video it's very much lacking info on chalkbrood.
Among
other reasons, there is the main one - the death of bees from viral epidemics.
This is well shown in the new film "So Said the Swarm"
why bees dont you sting you? what use do you
How old was the queen?

Where do you get that hat?
Dave gets them made up and sells them. 'Beekeeping It Real' is what he calls his own bee business.
UoG Honey Bee Research Centre, well I had a chuckle when I noted what it said. Got any contact info or website?
Hi Eric
Please send me an email at pgkelly@uoguelph.ca and I'll forward it to Dave. He does some clever t-shirts too.
Dwarf drones hatch from worker cell
Wait a minute. He said "its 23 degrees today" am I missing something. He's in a t-shirt!!
Hi There
We are in Canada! Our bees and beekeepers are tough. Actually we use Celcius here not Farenheit.
23 C = 73.4 F
It’s Canada, in Ontario it was +12 yesterday and I was in a tshirt!
Yeah you are an ignoramus who thinks the whole world uses farenhiet
@@brettjames9088 Well, no need to be the other species: an arrogantus.
@@HeartPumper sorry mum
Put your protections on dude this is bad habit for new beekeepers
