Mine just turned 18 weeks, and I've been keeping a watchful eye out. None at 26 weeks?! Holy cow! I'd always heard that they generally start at 18 weeks. I'll be so annoyed if I have to wait that long!
I read that they can skip till spring if they happen to mature at exactly the wrong time of year--if they were going to lay in fall during a molting season, and then they don't get enough light in winter, they can wait till next spring to lay.
I know exactly how you feel. Some of mine didn't start till 24 weeks, and the only way I could tell who was laying what was because they all lay slightly different colors. I was sure I was the only person on earth who got non-laying chickens, but apparently they will lay really really well once they get started if they hold off till next spring.
I'm playing the waiting game to. my 2 BSL's are laying an egg a day but the 7EE"S well they are starting to get their combs and wattles, it might be next spring before they start earning their keep.
Man oh man you are having to be one patient chicken farmer! Hope the girls are at least entertaining you while getting ready to deliver. And they will deliver!!!! Good luck w/ it.
Yep, peeps born late in the summer season may wait til spring to begin to lay. They will begin to lay large eggs once they start, without all the smaller pullet eggs.
Additional light in the coop, meeting the 14 hour requirement will get them going however.
