I made up a late season nuc to hoping they would produce a queen. Until yesterday I thought it didn't work. Well, I now have 4 queens, 2 purchased, 2 produced. The latest is, by far, the largest. Based on my estimation (amatuer) of larva, she's been laying for at least 7 days.
I know that color doesn't mean much, but her mother was dark, she's golden. So my question is size. Is that a criteria that matters?. Reliably?
