I have 11 chickens that are appropriate ages for laying. Five 3-year-old Barred Rocks, and six 1-year-old White Leghorns. Last summer, they were laying consistently, but they stopped this winter, naturally. For the past two or three weeks, I've been trying to encourage them to lay. Keeping the nest boxes full of hay, putting in golf balls as nest eggs. Finally, five days ago, one of my Barred Rocks started laying perfect brown eggs. I was thrilled, but now, she has been laying an egg everyday for the past five days, yet the others haven't started. I know that I should just "let nature take it's course", but I was just wondering if anyone had an estimation. I appreciate any posts. Thank you in advance.
