The chickens have laid their first dozen eggs over the course of about a week, maybe 9 days:

I believe that the lightest in color come from Durf, the medium from Trouble, and the dark from Miss Thing. A few of them are cracked at the tip; I suspect this is because they keep scratching all the material out of the nesting boxes before laying, exposing the bare wood. If I can find a plain coir doormat, I may cut liners for the nest boxes out of that and see if it helps.
