I raise honey bees and queens and I have looked here for this answer to this question but did not see one. I do splits from a 2 brood box (20 frames) parent hive to a 5 frame Nuc once the nuc raises a queen I let the queen start laying for a few weeks and transfer them to a 10 frame hive.
Now here is the question I did a split and accidentily transferd the queen to the Nuc and after about 4 days I noticed the nuc had fresh eggs laid so I looked and found the queen from the parent hive, If I put the queen straight back into the parent hive (after being gone 4 days) will they reject her and kill her or will they accept her back immediatly? For safety I put her in a queen cage with a candy plug. I have never made this mistake before and was wondering.
