I believe these are from my buff orpingtons , they are who I see in the boxes , I know it’s not from my polish ( they lay white eggs)
I have an EEer and a spitshauben
But they are so many shades I don’t know
How many orps do you have? How many eggs do you get each day? If you ever get more eggs in a day than you have orps then someone else is laying. EEs could lay eggs of those colors as well. Color can vary from bird to bird so it's possible they are all orp eggs.
