I think that if JP wants to raise meat birds, he should go with the Cornish broilers, they are ready for the table at 4-6 weeks old. They grow very rapidly, really fast. I know that fellow that grows them and because they grow so fast, their hearts have issues. He always puts the water at the other end of the pen so that they get exercise, otherwise they can have heart attacks. Sounds like they MUST have exercise, but they grow so fast. Here is something from the net, do a little research to find out what you want.
http://en.wikipedia.org/wiki/BroilerI am only dabbling in raising meat birds. The only ones that we have eaten so far, have been the Rhode Island RedXwith a brown egg layer, no speciific breed, other than called Sex-a-link. They haven't even began to look like they would have been worthwhile eating until over 16 weeks old, that seems to have made them rather tough. I am breeding for heavy weight dual purpose birds, but that is on hold until we get moved to our new place and set up. I am downsizing the birds at this time, I can't take too many with us because of unknown circumstance.
Irwin, canned chicken spread sounds delicious, gonna have to try that one day, hee, hee. Have a wonderful and awesome day, Cindi
