I know how you feel! I purchased 18 week old pullets thinking that they were POL. I got RIR, BR, BO, true Ameraucanas and EE. My first egg arrived when they were 27 weeks old and the last FINALLY laid at 35 weeks old.. I had thought I would never get eggs. I even thought my EE might be roosters (never had rose combs before).. I emailed the breeder over and over again, asked here--what I was doing wrong, did I need to change their feed, were they all roosters, etc. etc... But once they started it was like Christmas..and I finally realized--they lay when they are ready--and NOT one minute before.. I think so many people have read that chickens start to lay at 16 weeks-20weeks....that everyone expects them to lay during that age.. My uncle (who is 80) said he remembered his grandparents and parents-- setting eggs in the late summer so the new hens would start to lay in the early spring when they about 30 weeks old. IF they were born in early spring --they started laying in Sept/Oct --when the weather cooled off. He knew their age because it was his job to cull the roosters and spent hens for canning He said he never heard of a chicken laying at 16-20 weeks old until they 'came out w/ these hybrids'!
