I went out to the chicken yard about 2:30 this afternoon to give the girls fresh water, and to my surprise, I found an egg lying in the chicken run. Then I saw another, and another, and under the raised coop, another! What the heck are they doing laying in the yard?! Then I glanced at the pop door and it dawned on me that I hadn't opened it this morning. I had let them out the big door, closed it up, and forgot to open the little door. They couldn't get back in the coop to lay, so they did the best they could.
Sorry, girls.
