I just recently (2 weeks ago) bought 5 NHR pullets from a hatchery/chicken farm in CT. Well I bought them from my neighbor who went and got 20 of them, 5 being for me. He didn't tell me how old they are. They are huge compared to my 8 week old chicks and look full grown or nearly there. How old are the normally sold ready to lay pullets? I'm just trying to figure out how long of a wait I'm in for before I find that ever special first egg...
