It's just warm enough in the Vancouver, BC area to support a lot of different greenhouse (aka glasshouse?) crops.
Thye buy carbon dioxide from the breweries (yeast farts) to fertilize the greenhouse air, to about 3%, I'm told.
Then, it turns out that bumble bees are the most enthusiastic pollinators for these crops.
Was a lot of BC university research with the bumble bees, not that many years ago.
Large size store eggs here are $2.99/dozen. Local farm eggs, mixed sizes, some double-yolk, are $4.00/dozen.
I buy both. I don't think it's an exaggeration to claim that the farm eggs have 2X thick shells.
