Last Sat I bought some chicks from our feed store. I got 9 standard breed pullets and 3 Cornish Xs. I've only processed standard breed or mixed breed roos before but have heard such rave reviews about the Cornish Xs that I just had to try them. I thought this would be a good way to get experience with the breed, instead of being overwhelmed with 25 of them at once. I thought I could keep these 3 together with the others while they're little & fuzzy, then when they feather out & can be left outdoors at night I'll separate them and finish raising them in a small pen of their own. Right now I'm putting all 12 out in a baby tractor in the grass during the day, and bringing them onto the patio after dark. They have water but not feed in their box at night. They're only 1 week old and already the Xs are visably larger, and I'm noticing more poo in the grass & in the box than usual. They're eating Flock Raiser, because I'm feeding ducklings now too. At what age do you think I should separate the Xs from the others? And at what age are they ripe and ready to process?
