Two nights ago I went out to make sure the chickies were in for the night (and that Gracie was not on top of the fence).  I had to walk to the back side of the bush in the dog run to move them out from under the bush.  Lo and behold, there was a tiny little egg.  I'm fairly certain that it was Carly who laid the eggs.  She had the funny little squat going on.  Then I remembered seeing her on the the side of our little garden shed (which is about 6 inches from the fence).  Sure enough there was another egg.  It was a tight squeeze to gather that one!
