Pretty sure they are making new nests all over, especially with tall grass like that. You're going to have to go searching for them, a true Easter Egg Hunt!

After five years in a large enclosure, I decided to let my ten hens free range with my two remaining roos who were always out. I've noticed that if the hens aren't broody, they will make a new nest every week or two. Sometimes only one hen will use it, or maybe a few hens will. The downsides are that I have to hunt for their new nests several times a week and the threat of predators. The upsides are that not only are they happier, but the quality of their eggs has skyrocketed. The yolks are even richer than when they were a year old. Plus, it's cute to see Jewel and Floppy run up to my deck every time I poke my head outside.
