Over here there is always a lot of debates about which parent gives what quality to there offspring.
In general it is said that the male passes on egg laying and female body shape / meat yield.
But if this was entirely the case we would never use Cornish males in our crosses only Cornish hens.

I think that is an over simplification of chicken genetics. What the "experts" say does not always occur. If it was just one gene controlling body size and type what you're saying might make sense. It is not. There are 2 genes for every trait. Many traits have more than 2 genes controlling them.
I had a CLB rooster that had pea comb, if you listen the experts they say two single combed parents cannot make a pea combed chick. It happened. I understand as well as anyone what the punnett square shows us. I also know there are exceptions. mutations and injuries that can do anything..
So basically, I say "nah, using all hens would not do it,...."
