We butchered a couple of extra roosters yesterday, and they turned out great! One was a 14 month old Columbian Wyandotte, and one was a year and a half old Easter Egger rooster. Even at there ages, they were pretty tender and they tasted wonderful! So now I am about to start building a chicken tractor to raise meat birds in, and I am wondering which breeds to raise. I am debating between a good dual purposed chicken, or the cornish crosses. So I have a few questions- 1.) Which is the best meat breed for free ranging/moveable tractor? 2.) How big should the tractor be to raise about 25 to butchering size? 3.) Can I mix corn with grower mash to reduce cost? (about 25% of what I feed to my layers is corn, is that ok for meat birds?) 4.) If I do decide to raise a dual-purposed bird instead of the cornish crosses, which breed is the best? Thanks all! Oh yeah, I thought of another one- 5.) How tall should a tractor be for meat chickens?
