The egg count is going up and down like an EKG
out of 4 hens who usually lay 3-4 daily, I find there are more days with only 2 eggs in the nest box. The largest hen (Large Marge) has a REALLY full feeling bottom side that the others don't have- enough that it seems like 2 eggs could fit in there. Could she be backed up on eggs coming down the chute?
