I was in conversation last week with a RBI and he told me that his association had had considerable bother with queenless starter boxes. However they had had good success with queen right hives as starters.
Now that is the direct opposite of my experience, which goes to show if one way fails for you then for goodness sake try another as that may well work, and if not well try yet another. There are many different ways of working every aspect of bees and there will out there be one which will work well for you. Try and try again is the motto to adapt.
Just remember that not all advice on the web is well meant. Having just said that the advice here IS.
Time to start thinking about mice and how to reduce the local population, and to keeping the little horrors out of your hives.
