My 101 Colored Range Broilers (Freedom Rangers) from JM are 17 days old now. They've been joined by the control group of four cornish x that are within a day or two of the same age. (And I've got my 14 Delaware, Ameraucana, and red sex links in with 'em as well for the time being; the Delawares and Ameraucanas are about a week older, but similar size now.) They are all eating starter/grower, and eating a LOT of it now. They are presently in a 10 x 14 stall in the barn, and will move out into range shelters protected by electro-net when they are feathered well enough and the weather cooperates. (And I get the shelters built.) I am pitching hay sod into the stall for them as I break ground for the veggie garden, so they are learning about natural foods. They will have essentially unlimited fresh pasture after they move outside. I have an order placed for a half-ton of 20% broiler feed, which the guy at the local feed mill is going to custom mix for me. I'll be picking it up May 11. Will a half-ton be enough to bring 105 chicks from age 3.5 weeks to slaughter, which I project will be at about 11-12 weeks? (I'll probably do the cornish x significantly earlier. The little dodo-birds are already worrying me with their Cartman-esque physiques.) I thought a half-ton would be plenty, but seeing how fast they went through the last bag of starter, now I'm not so sure. I can add more feed to the order now, but need to get a revision to the mill before they mix it for me. Should I get a few hundred pounds more? Also, I've read here and there about "finishing on scratch." Thoughts on this? What is the advantage? How long do you feed the scratch?
