I can't comment on the roo/pullet question but I have a silver comet/red star/RSL- and she is fabulous. By far the most tame of all of our chickens, because she was hand raised by my sister. She is super quiet- the only time I hear any of them is when they want out of their coop in the morning. She lays and egg everyday. And my 3 yr old can walk out into the yard and pet her. If they are hens- they could be fabulous too!
