glad you found the "stash". Hope you are able to identify the culprit (s).Someone WAS hiding them! I found the corner of an egg sticking out from under the nest boxes from the little coop. I had pulled some grass to refresh the nest boxes and was putting it in them when I noticed the one sticking out at back of little coop ..... Went around to pick it up and saw 5 more hidden underneath the nest boxes on the new pine chips I had scattered after the roof was on the large coop!!!!
So I don't know if I got one a day for the last six days or two each the last three days. I took 4 and left one and put one in the nest box in little coop.
Now to wait and see.....
