I think I now have four layers. I want to know who is laying what egg. Has anyone ever tried color hair spraying a chicken's bottom so it would transfer to the egg to identify? Someone suggested food coloring the vent but I thought this idea might be less invasive. If any of you are good at identifying eggs: I have two laying peachy colored eggs which I am thinking are my Buff Rocks One is tinted (cream) - no idea. One is brown but not really dark. Just darker than the peach ones. You options are Delaware, Black Austrolorp, and Salmon Faverolle as well as the two Buff Rocks.
