I'm not sure if I can trust what I read. The information is so conflicting. If anyone has experience with these breeds of chickens, I'd like to hear your stories. I have 4 chickens, each 16 weeks old now (leghorn, RIR, black sex link, red sex link). I just found an egg this morning on the coop floor, the first one. But I don't know who it belongs to. We're suspecting it's the red sex link because she's squatting a lot now when we go into the coop. The others don't do this. But the books say the black sex link should start laying at 16 weeks. Not sure what to think. I know I'll find out in good time, I'm just curious.
