I have four hens who are producing eggs. My RIR and ameraucana lay faithfully - 4-6 eggs per week. My two Buff Orphingtons slowed WAY down - 2 eggs a week each, or less. Not egg bound, but scraggly looking, so I figured - Molt. I am back to three eggs faithfully, so one of them has started to lay again, or both, just not as many eggs. It's picking up, though. I think it's the summer heat and potential molting that is affecting mine.
