We have free range rouens. One of the hens has been on a nest for a few weeks now. I would guess that we would have had babies within the next week or so, maybe sooner. Some time during the night, all of the eggs disappeared. No shells or anything. I'm not exactly sure how many eggs there were. I think somewhere around 10, she kicked 2 out last week. What could have taken that many eggs overnight without a trace?
