I have nine 18 week old and ten 17 week old Red Sex Link girls, (And many other girls of ages ranging from 14 -16 weeks, all brown egg layers!) I got my first egg, brown in color, well really 1st, 2nd, and 3rd egg today. All were in the nest! I really don't think all three girls would start laying the same day, so my guess is there have been some laying outside while free ranging, and once the first one used the box, the others followed suit! What are your opinions?
