I found a white egg in my run about a week ago. All my girls are brown egg layers- Dominique, Wyndotte, BCM. The run is fenced and has wire on top. It is also inside our fenced backyard. Anybody have any ideas? Our neighbor has one black bantom who does fly over their fence occasionally. I found her in my yard yesterday. She is very shy, no one can catch her. It seems unlikely she would have gotten into my run much less stayed long enough to lay an egg. What do you guys think?
