Red Ranger Meaties 9- weeks

Have you had these before? I'm on my fourth batch of Red Broilers from Ideal. This batch seems faster growing than any other. Could be feed or weather since we've moved from AZto NC.
I'm hoping to get Dorkings to raise but the Red Broilers are good and will work until I have a Dorking flock going.

 

They look very similar to mine. They tend to have bigger thighs and legs, slightly less breast than a CornishX. I usually wait until 12-16 weeks. One thing I really like about them is that I can process 2-3 at a time and not worry about the others dropping dead. Each batch I've kept a pullet or two and they lay large brown eggs. I've lost the 1-2 year old hens to heat a couple of times but they're pretty healthy chickens otherwise.
I've also found them to be far more active then Cornish X, very good foragers. The only thing I don't like is that the cockerels can be total but threads when they reach puberty but what do you expect from a pen full of young cockerels with plenty of laying hens to fight over?
I pick out the most obnoxious to process first and just work down from there.
