Queen rearing gone wrong again?

[sean-a]

Any help appreciated,

I found some queen cells and did an AS, tore down the queencells and put some some grafted cups in to replace the queencells I destroyed.
My first attempt at grafting failed completely 0 from 19 !!

I then put in another frame of eggs (about 14 days ago) and they drew 3 queen cells.
I left 2 and put a third into a cage in the airing cupboard.
Checked this morning and a cell in the hive has hatched.
The cell in the airing cupboard has not.

Should I try to open the cell?
I was really hoping that it would hatch.

Needs to be 35.5c to hatch with 50% humidity, so airing cupboard prob not adequate. Get a cheap egg incubator and use a bit of melted wax to stick cells in vertically as in a hive. Worked recently for me and with 2 queens hatched from 4 QC's. Yep, do a post mortum!

I think that 50% is low for the humidity, mine was set for 60 to 70%.

Gentlemen, eggs hatch, queens emerge...

Perhaps egg emerges when it comes from abdomen.

Anywhere in that area is good. 50-70% RH is quoted in most books.

If only, the issue here is the lack of emergence.

Thanks for the advice fellas.
I have not kept the temperature right and humidity too low.
I have a few roller cages so should have stuffed them back in the hive.

I will know better next time.

And thank you Beefriendly, I will not trip over my vocabulary again, precision in all things !
