This queen was purchased from John Gates Apiaries. I used her eggs to raise a few queens this spring, using the OTS method. I like the plastic frames, always true and square, no assembly required, don't blow up in the extractor. You just have to be more gentle with the ears than the wood ones. this year I started painting the foundation with wax and it has made a tremendous difference.
The was is so white because those caps are less than a week old, also because it's a Nuc in a 10 frame deep, there is no traffic to the second box.
