I discovered the other day one or more of my girls is eating the brown eggs. Not the EE's eggs, just the brown ones. We only have 2 birds laying right now. The rest are holding out on us. So I posted on what to do, and a few mentioned to put golf balls in the boxes. I did that and now the EE is laying on them like they are hers. She went nuts when I went to check the nest box for eggs. What a riot!! She makes a great golf ball warmer.
