Hmmm.....once they start laying, isn't it a go go that it will continue? Not sure which one did the laying and they free range during the day.
When my hen laid her first egg, that was it for a week. Then she laid more and more days. My other three hens didn't lay every day for a few weeks either.
Mine didn't lay everyday at first and if they are free ranging they probably are laying somewhere you haven't found yet!
