My ee started laying last tues and has only missed one day since. The eggs are a little bigger than a silkie egg. Today when I was out there cleaning she went in the nest box and stayed in there. I left and a couple hours later my son went out and brought in a blue egg that's almost twice the size of the other ones. Is it possible that it only took a few days for them to reach that size? Or could it be the other ee laid it?
