1) Yup, done all the time. 2) One can purchase a Cornish X for much less than $2, just shop around. I find that I can raise the CX for much less than any other bird out there. The CX is the most feed to meat converter of all chickendom. Also, time is money and one's labor has it's costs ... One can process the CX at 35 days for a 1-1 1/2 lb game hen, at 6 weeks for a 4+ lb frier, or 8 weeks for 6-8 lb roaster, or 10-12 weeks for 10-14 lb roaster. While it will take one 18-24 weeks and about twice the commercial feed to get a 4-6 lb carcass for a DP. Then too, it is much cheaper to house a processed chicken in the freezer than feed a live one for quite a few extra weeks. 3) One can process the CX at such an early age that there is little need to vaccinate them. One will need to educate, understand, and follow the proper protocol for management and the rewards will be great. As the old Scottish proverg goes... " The eye of the master fattens the cattle". Good luck !!!
