Hmm, I wonder if any of the eating eggs would hatch? I have read a few anecdotes of people hatching grocery-store eggs.
Whether any of the eggs are fertile would depend on whether they deliberately keep males (probably not) and whether they have any oops males in the flock (depends on whether they think it's worth the time & effort to catch any males that may be present.)
I notice their list of products includes size medium blue eggs, not size large or extra-large (which they do have in brown eggs.) So the Azurs might not be laying eggs as big as you might like.
