We have two in our laying flock. Dora started laying at 7 1/2 months, and Muffy started about three weeks ago, which makes it about 10 months. It seemed like forever, and I actually thought that Muffy was laying brown eggs, but as it turns out, the brown eggs were from the undeclared (possible closet rooster) hen that started laying late, as well. One lays beautiful mint-green, the other, is an olive-egger. We have three more in the brooder and it will be interesting to see what they lay and when. I am hoping that they lay sooner, as we got them much earlier in the spring, so the days will be getting longer for a longer period of time in their development, if that makes any sense.
