How long can a frame of brood (1 day old larvae) be kept out of a hive and still be grafted for a viable queen? I have a hive about 20 minutes from my house which I had planned on moving to my house but for various reasons cannot do so now and I want to use it as my donor hive. I will be using a hive at my place for cell starter colony by the cloake board method. Can I just transport a frame from that hive to my place and then graft from it, or should I create a small temporary nuc and then recombine later?
