I stuffed up big time.
When I make up nuc's I place 3 frames with mixed brood in a 5 frame wooden nuc box and add a frame of honey if i feel they are a bit short on honey.
I move this box to another yard - fieldbees and all.
Generally they make their own queen. Generally they don't need feeding.
This time I used boxes with a conventional slot entrance and I had nothing with me to close them off.
So, big mistake, I left them in the yard with the mother hives.
Of course most of the fieldbees wil go "home" to the mother hive.
Without field bees the some of the nuc's run out of food and I will loose a couple.
I did feed them but was probably a day too late.
I made up more nuc's today....and, yes, i shifted them. I also gave them a frame with honey...just in case.
Due to age related issues most of my hives i take brood frames from only have a 1/2 super on top. I'm still able to lift those with honey - no chance anymore with the FD supers.
The disadvamtage is that I can't borrow honey frames from the honey supper/
Never stop learning in this game.
