Pullets normally wont show that big of comb and waddles at 6 weeks. Note the thickness of the legs on your boys too. I've had several breeds and waddles appeared around the 9th week. My one roo this year had waddles starting at 4 weeks and is 7 weeks now looking much your boys. He's a blue Orpington.
Find pullets that are as close to the same size as you can. As it's Claudia Jeans home turf she'll have the upper hand so them being a little larger wont matter. Finding a breed you want of age will be tricky but doable if your willing to travel for them. Craigslist is an awesome resource.
