I consistently get 7 eggs from 8 girls. I don't know if one is not laying, or they alternate days skipped, or if one is laying somewhere else. I used to get 8, but now only occasionally. I've looked around, and can't seem to find another hidden nest. I did find 5 eggs on top of hubby's brush-hog, which was covered with a tarp, but I keep checking there, and they haven't done that since I removed those 5. (I noticed a hen in there, and didn't check it for 2 weeks, so I have no idea how old those 5 eggs were... they got tossed, of course)
But yesterday, I got 6 normal eggs, and one really tiny egg. About quail size, but perfect otherwise! I think the amount of daylight is starting to affect them.
