Hi
I share the same thought about only using the bird for flytying
I am working on making my own bird for meat, eggs, and feathers
but this is a very slow process and you need to have the right genes, space and time
The flytying birds you see available for sale are specifically bred for feather quality
If you want a bird for other qualities you just cross to a type of your choice and go from there
This is what I am doing
If you want to know how those genetic birds taste I don't know
other than I eat my roosters I raise with no problem
most are tender every once in a while you get a tough one
but this is for the birds I raise
most of the birds I see for flytying are between 10 months to over a year for slower growing roosters
we also have several members here every once in a while sell eggs
you can go to

and go from there
