My barred rock started laying at 22 weeks and has been faithfully laying almost daily, but my other four still aren't laying. They are 26 and 27 weeks old. I have a GL Wyandotte, BO, Black sex link, and an EE. They all seem to be maturing a lot slower than the BR did for some reason. They all get along well and everyone eats like pigs. Over the last couple weeks they all seem to look like they're ready to start laying, but still aren't. I understand they all mature at different rates but it's wierd that they are all still not laying. I live in north Texas and its been a little cooler lately, in the 70's mostly. Do you think they might not lay until spring with the daylight only being around 12 hours or so now?
