We ordered our spring batch of Cornish X's from MMH also. They grew to be between 8 and 9 pounds dressed out at 10 weeks. They are very hardy too. Enjoy!!!
We have cornish right now too, 2 1/2 weeks...those little things are about to eat us out of house and home!!! This was my first time with cornish...I hope it all pays off in the end because it has been one stinky ride!
