Bresse chickens are unique and rather rare. They are supposed to be the most delicious chickens to eat, though I've never eaten one, and don't think I ever would. However, the price for a dozen Bresse eggs does not seem to be out of the market range. See these ads;
1.
Hilltop Farms (I believe it's $10/egg = $120/dozen)
2.
Bresse Farms seriously undercuts this, though at $45/dozen
3.
Better with Thyme is still a bit cheaper, but in that range, at $40/half dozen, or $75/dozen
4.
Pivot Farms with fertile eggs, charges exactly $50 for a half dozen
5.
Greenfire Farms (the original importer, I think), charges $12/egg, or $144 for a dozen.
