I'm thinking about doing Freedom Ranger chicks-- they have better mortality rates than CornishXs, though they may not get as big. They are generally processed at 9 weeks for 5 lbs birds or 13 weeks for broilers (8 lbs on average, I believe). Processing (when not done yourself) generally runs between $1-$2 a bird.
So, if anyone is interested, please let me know. I'm unlikely to do this myself, as there is a 25 chick minimum and I have laying chickens in the incubator and a 24 bird limit where I live :).
Meat chickens need lots of water and feed that is about 22% protein (can be purchased at most feed stores) and can free range on grass with table scraps, etc. (Despite what "free range organic" eggs claim at the supermarket, no chicken is a vegetarian, so they are great as garbage disposals :)) As a 9-13 week project, it's a cheap/interesting way to get better tasting meat. The non-meat home grown roosters we've had have had enough flavor improvement to be very much preferred over the store bought ones. Plus, we have the option to avoid medication in our meat this way.
So, let me know if you're interested and we'll see what we can work out.
In the meantime, if you want any rare-breed laying chicks let me know and I'll see what hatches. They're due this coming week. They'd be straight run (unsexed).
