I have different ages. The EE was my youngest layer, at 20 weeks. The Australorp started laying at 24 weeks, the BO at 25, and my GLW at 27!That's eggciting! When were your girls born? I'm waiting on my Araucana to start - just worked it out and she is 21 weeks tomorrow - definite reddening of her comb the last 2 weeks am so eggcited for my first blue egg.
My RiR is 22 weeks, and the most recent layer. I have 3 SLW and I am expecting them to wait another month to start.
