I have 11 pullets. 3 are easter eggers that I got almost 2 months after my first 7. Out of the 7 that were born June 1, 3 have started to lay. They started about 1 1/2 weeks ago. They are: 2 white rocks, and 1 red star. The others 4 are two buff orpingtons, and two barred rocks, which have not laid an egg yet. I am wondering why. I know they all start at different times, but they have BIG red combs and wattles, and have been doing the "squat" as long as the others. Why no eggs from them yet???
