I was reading https://www.backyardchickens.com/forum/viewtopic.php?id=12691&p=5and saw some very interesting things. - There's a big growth spurt between 8 and 10 weeks, and they could potentially hit 10 lbs (maybe more?) - These birds are intended to live at least 81 days (12ish weeks) That's PROMISING! I can totally get behind the idea of some jumbo birds, if they're healthy and happy to let grow that long. My questions: 1) How long can you let them stay alive? How long do they keep growing/at what point will the weight max out and just have them eating food with nothing to show for the expense/time? At what point does the flavor/texture start to degenerate? How long can I stall in order to stagger processing over multiple dates? 2) How will the amount of food in the later weeks compare to the earlier weeks? I saw: "b) The ammount of feed to go the last couple pounds puts you on an upward swinging exponential curve." but didn't *really* understand too well. 3) How do these birds do for "cornish hens"? (I don't know what you'd call a 1-2 lb bird that wasn't a cornish chicken). 4) I bought 100 "color rangers" from JM hatchery (super friendly customer service, btw!) and will be getting a mixture of colors. Is the difference between colors really THAT pronounced, and if so, which birds am I better processing for "cornish hens", fryers, roasters and jumbo monster chickens? 5) If I'm doing a flock raiser type feed (I was looking at a homemade recipe for it, actually), the winter recipe included a midday mash that includes meat, but no details on what "meat" means. Can I go to the butcher and get tendons and scraps and to the fish store and get trimmings and heads and grind those and add them in? If not, what do I use? And how cold does it get before this winter addition is started? They're going to be free ranged days and cooped at night. Thanks!
