Ok I have 3 RIR hens and 1 rooster & I have had them for a year now. They started laying last september. I got the hens from the feed store and raised them in the house till they were big enough to be outside. So my favorite hen Scarlett loves to be held but the others cant be bothered even though I raised them all. My question is when do RIR start sitting on the clutch? Someone told me that the RIRs wont sit until they are older is that true?
