We have 6 leg horns and 1 BR"Ethel" and 1 BO "Lucy", The ladies are all in the same coop and have been for several months. The Leg horns are not very nice to Lucy and Ethel and I am wondering if this is why they are not laying yet. the 6 Leg horns started laying in September and Lucy and Ethel are about 2 months younger so we thought we should start to see eggs soon. We see their feathers in the box where the others lay but no brown eggs. Do BR and BO's take longer to start laying?
