I have three. Coco and Pepper started laying at 19 weeks and 20 weeks and soon dependably laid an egg a day until the days were too short. They both did so again from about early February until they started molting about the end of September. They laid through their molts, just at a lower rate - gradually down to about every second or third day. They just about got back to a egg almost every day when days got too short again.
The next year (this year), they started a few days later in the spring. They both laid almost every day through most of the summer but not as dependably as before and gradually skipped more days. They haven't started molting yet.
Mocha started a few weeks later, stopped for the winter a week or two sooner, started up in the spring a week or two later, stopped while broody in June, fell off for molting a week or so sooner than Coco and Pepper, stopped for the winter a couple of weeks sooner. This past summer, she didn't go broody. I think she stopped laying already for either molt or winter.
Coco is about twice as heavy as Mocha. Pepper weighs just a little less than Coco but I haven't weighed them.
I think they are friendly but I don't expect to pick them up or pet them. We do quite a lot of murmuring to each other. They like to be close to me even when I don't call them.
They are much less flighty than my brown leghorns.
