Hidden Nest

[wrightka]

I have a White Leghorn who continually gets out of the fence and back in to lay an egg somewhere in the neighbor's unkept yard. Sometimes I come home for lunch to see Dumplin rummaging for grasshoppers or taking a dirt bath, but when I get back from work she is back in her pen. I am debating clipping her wings, although I don't want to, but that doesn't help me find her nest in the neighbor's yard. Any ideas how to track down where she is laying? I also have 3 Easter Eggers that are 5.5 months and not laying yet, so I suspect they may be in on the nest too.
Thanks
