I have kept an egg journal since Jan. 1 this year. I have gotten as many as 61 eggs and as few as 48 eggs from ten one-yr-old hens. The average is about 56 per week from those Girls. My breeds are Rhode Island Red, Buff Orp, Silver Laced Wyandotte and Barred Plymouth Rock. Maybe those numbers will help. My Girls are very good layers so I think that 48 was only one week since the first of the year.
