Thank you for that information. She must have buried the eggs while she got up to eat then by the time I got out there she had gathered then up and put them back under her. There is still a total of 2 eggs missing so I hope your right and they are just under her wings. I decided to enclose her big nesting box shes in just to be safe. I noticed the rooster and other hens jumping in with her.
It is also possible that the eggs which haven't returned were bad and the hen ate them... they will do that on occasion, somehow the hen senses when eggs aren't viable and rather than risk them breaking in the nest she will eat them, shell and all. Some folks may find a bit of egg yolk residue on other eggs, sometimes the egg just disappears with no viable culprit other than the broody herself.
