I wondered the same thing so I keep checking under the coop and in every corner of the coop...nothin'!
We have an egg!! Woohoo!!! It's been nine days since she laid her last one. And other than her vent being red and swollen, she seemed fine. Full of energy as always. But I kept an eye on her anyway. This morning when I opened the pop door to let the girls out, she was right there to greet me as usual. So I pinned her to check her out. Vent was back to a healthy pink. And sure enough there was an egg in the coop. Now of course I'm making the assumption that it was hers. I do have a BR that could start laying any day now. And this egg was more pinky brown than the toasty brown my red star usually lays... But, I'll take it!
