When do different breeds start to lay?

[kittykorat]

I am new to chickens- I have a couple of types...
A white rock, Australorpe, and a few EE's. They are about 11 weeks. When should I expect them to start to lay? Are there signs to look for?
I haven't built the nesting boxes yet, cause I know it will be awhile..

When they are getting close their combs and waddles will develope and turn red. Also, they should start squatting. When you go to pick them up or pet them they will squat down and put their wings out in submission. Once you see those things, you should have eggs within a few weeks. If you are not lighting the coop they may not lay until the days start to get longer. I wouldn't expect anything before 20 weeks but you never know. Good luck

Our Austrolorp and Java just started laying this week. They are between 21 and 24 weeks old. The Austrolorp began singing an "egg laying" song about 2 weeks ago and her wattle and comb turned very red. The Java was less vocal before laying, but definately seemed "friendlier" - started following us around more. She did not start "singing" until after she layed her first egg. The Java barely has a wattle and has a very small comb, but both are red. The Austrolorp is smaller, but looks "more developed" with regard to her comb and wattle.
