I have had RIRs and my Rusty did not lay untill 24 weeks, she had huge wattles and her comb was pretty impressive as well. I orginally named her Penny but since she did not lay and the wattles were so large I figured I had gotten a roo as well. Rusty was a fantastic layer. She laid large eggs from the getgo and laid for 18 months without a break. She went through quick molt and was back at laying within 5 weeks in the dead of winter. A very nice lady who has bought some of my chickens finally talked me out of her recently. She was 3 and still laying 4 eggs a week.
