Well I got a nuc almost two months ago and in my first or second inspection I must have smashed the queen because about 3 weeks ago I found 6 emergency cells 4 on one frame 2 on the other so I grabbed the frame with 2 cells on it and a frame of stores with the accompanying bees and stuck them in an empty box and stuck a follower board next to them to close them down yesterday I saw my little makeshift mating nuc bringing in pollen so I checked it today and every available cell has an egg in it and in a good solid pattern I gave them another empty frame and closed them back up
