You aren't making cheap chicken, that's for sure. We figure that one Cornish X will cost us $12 in feed over the 7-8 weeks it's alive. 7-8 weeks is the norm, you could let them go as long as nine weeks, but in those later weeks you're putting more and more feed into them for not as much weight gain--your growth curve has flattened out so you're needing more and more feed per dressed pound of chicken.Meaties should get 20% protein?
How do I add more protein to my mash?
I ran into this http://ramblingredneckmom.blogspot.com/2011/04/how-to-process-chickens-at-home.html
"They are cornish cross from Tractor Supply. They are seven weeks old, about the average age of all the chicken you get in a store. They are fed a 20% protein feed, no medication/antibiotics/hormones etc. These guys eat a LOT - in seven weeks, one dozen consumed about 200lbs of feed."
doing the math That's about $50 in feed for a doz for 7 weeks (assuming 7 weeks is the norm?)
20-23% protein is correct. To up the protein, the easiest way is to use a Purina Flock Raiser type product that is 20%, or a game bird feed. Our local company makes a 35% protein supplement that we add to ground corn to bring the protein back down to 20%.
