Sometime you'll want to move some brood to another hive. As has been said just pull it out, make sure the queens not on it and put it in. All bees will always accept free brood. Now if you have to move it very far say to another yard it has to be kept warm.
Take a small cooler that the frame will fit in, microwave a large burrito until its HOT, put both in the cooler and drive to where your going, install the frame and eat the burrito.
As a side note I've done several combines. I very rarely use newspaper I just set the queen less on top. Yes they fuss a little but there's usually not enough dead bees in the morning to cover the bottom of a coffee cup.
One time and one time only I added two frames of brood with the bees on it to two other frames from a mating nuc that the queen had started laying and they killed the queen. I've done this several times and it had never happened before or since. They raised a new queen which I still have.
My theory here is that the bees I added were stronger than the original bees. I don't normally put in two frames at once rather one a week.
Just rambling here. Woody
