I remember having those SP/BR cockerels hatch here with their sister, Raven. I had three of them and I thought they were BR pullets...for about four weeks, then the red combs started showing up. They were very sweet, friendly birds! And my CJ looks like your Ameraucana cross, doesn't he?
I haven't spoken to that guy in a long while as I haven't had any trouble selling PB BR roos at the age he requires them (16 wks +) by private sale. He does still have chickens though, so I assume the answer is yes.
Also, there's another guy who will take very young ones off your hands just down the road from me. He'll take them as soon as they are ready to be out of the brooder. Of course, no profit for us, because he has to raise them.
