I just ordered 50 KK from nolls hatchery at .75 Cents a bird for all Roos. They claim they will 5 lbs average in 8--9 weeks. When I get them (1st Week of Sept. I will keep a log to see how they do) I am also going to order some Rosambro from from MT-DI and see how they do.. Just thought I would try something different from CX and FR. Both are much less expensive than FR.
