My girls are 27 weeks old, red faces and combs. I've had one squatting for 3 weeks. They just don't lay eggs. I have fake eggs in the nests, haven't even shown interest in the nests. I didn't expect the Brahma to lay for awhile yet, but the others look and act ready. What the heck? Breeds are: cuckoo Marans, wyandottes, Brahma and EE's.
