Here's my "when I was a kid moment" chickens weren't expected to start laying until 6 months up to a year, now with rations and sex links and improved breeding these chickens laying at four months seems crazy to us old folks. I'm not in any hurry to see mine lay, so I slow them down a bit, something you can't seem to do with these newer sex links, I still prefer the slower big girls, they have staying power.
