It's so funny that you posted this--I've been spending a lot of time browsing the Practical Poultry magazine's forum, and learning lots of differences in British terms and breeds and ideology of chickenkeeping! That forum was the first place I ever heard of Ross Cobs, and I did notice that the grow-out time was much longer than American broilers, but that they seemed to be the "broiler" of choice among people raising meat-birds in the UK.
Something else I've noticed that seems to be a fundamental difference in attitudes over eating chickens is butchering age. Lots more Brits than Americans seem to raise dual-purpose purebreds as their table birds, but with a major difference: If you read this forum, you'll see repeated statements that purebred roosters must be butchered by the time they're 12-16 weeks old or so, or else the meat will be "too tough" to be palatable. Over on the PP forum, on the other hand, you'll see repeated statements that these very same breeds must be grown out to at least 22 weeks or more, in order for them to achieve their full size and especially "full flavor."
I find it interesting that the main criteria for determining processing age here seems to be the texture of the meat, whereas over there the main criteria seems to be the flavor of the meat. And I can't help but wonder if we've got the wrong end of the stick on this one!
My family is going to attempt to put aside our notions of what "chicken" tastes like (from years of eating those jumbo Frankenchickens), and test the "tender vs. taste" factor at the end of this summer. We have some Buff Orpington cockerels who are 10 weeks apart in age, so we're going to process them on the same day, age them in the fridge the same, cook them the same way, and compare them. The older one will be 22-26 weeks old, and the younger ones will be 12-16 weeks old. We'll also be processing some White Rocks and Marans cockerels around that time. Should be interesting!
