Having had Rhode Island Reds for a few years now, we branched out and got 3 Plymouth Rocks, a Black Rock and a Delaware, to go with our 5 RIRs. After a bit of initial upset, most seem to be laying regularly, though we never get 10 eggs from our 10 hens in one day. I don't mind if they don't all lay every day, but my concern is over our Delaware - to my untrained eye, she has not matured. Her comb is still small and light in colour. We have always taken a large, red comb to be a sign of maturity. Ours looks like this: Rather than this: I'm not certain which hens are not laying, but based on the above info, I am assuming it's the Delaware. Am I wrong? If not, is there anything I can do? Help!
