At what age do chickens lay eggs?

[AK BartGirl]

I have 5 black sex-links, 2 Aracuanas, and 3 White Plymouth Rocks, and I'm wondering at what age they will lay eggs. Thanks for feed back

Your rocks and sexlinks will begin laying right around 20 weeks... give or take a week or two.

The Easter Eggers sometimes take 30 weeks.

Good luck!

Oh, and by the way,

My black sex-link started laying at 17 weeks. My golden comet started at 16 weeks.
