Re: bone head split so far, somebody save the day.
Glenn, the emergency cell in the first picture did not look that dinky too me. Remember that the cell is actually half an inch longer when you consider the horizontal part. I have full sized queens come from cells just like that one. Capped on day five is ok, day four is not.
I know we disagree on the use of pollen sub but you might want to try adding some on your next spilts to see if you get more cells. They will only make what they can feed and it is pollen that is needed to make royal jelly.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
