Grubs not capped

[Robbie & Jans Bees]

I wonder if anybody could tell me please, last week we put two frames of sealed brood into a weak hive from a very strong hive we inspected yesterday and it seems some of the grubs are not in the cells corectly almost poking out as if the cells are to shallow for the size of the grub.

The queen is in there but she seems to be very small but is laying all be it not a lot at present. The hive in question is a top bar hive I made during the wintre, do I remove the three frames to a nuc and let it build up or just suck it and see

Hi, if you mean that some of the sealed brood (probably towards the bottom corners?) is domed/raised then it will be drone brood I expect.

Hi Robie and Jan,
If the brood you put in was sealed then the bees must have uncapped it. Probably chilled brood through putting in more brood than the bees could cover. Apparently, emerging brood must be just that coming out of the cells!

Just read the title saying "not capped" - in that case sounds like what Beano says. If it is a small colony wanting to build up & if food scarce they sometimes uncap the drone brood and remove these bees as they consume resources and don't do any work. Sometimes they eat them.

It could be a number of things;
-bald brood - an occasional viral thing sometimes associated with varroa
-wax moth damage uncovering the brood
-chilled brood in the process of being removed as Beano said

However, if you emailed your bee inspector with the sentence: "it seems some of the grubs are not in the cells corectly", then he/she would be round like a shot suspecting EFB.

Any chance you can post a photo.

Sounds like drone brood on the point of being sealed in (probably if you checked in a day or so they would be capped)
It could be you have a rather scrubby queen in there - mybe she didn't mate properly? if there's not much brood i wouldn't be expecting her to lay drones yet.
Or it could be as Beeno said if the brood was capped last week.
Maybe not enough bees in there to cover all the brood in this cold weather

hi both,
with out much doubt the colony you put the brood in was not upto that much brood and it now chilled there are several reasons why it is unlikely to be EFB but the quickest eay to find out is to put the brood back in the orginal colony and they will soon start to remove the dead brood (of all ages,so not the foulbroods) this will tell you it was chilled/neglected brood.

Did you allow for the higher top suface area heat losses of a TBH by adding insulation? You will need more bees per unit area of brood to increase heat input or more insulation to reduce likelyhood of chill brood.

ANY suspicion of EFB should be reported

Yes, but:

almost poking out as if the cells are to shallow for the size of the grub.

Sounds nothing like a larvae not lying correctly in the cell - sounds just like an uncapped drone larvae

did it look anything like this?.....
