heredity in chickens

[3riverschick]

Has there ever been a study done or does anyone know the inheritance % for certain traits?

This book addresses the issue:
Inheritance in Poultry

The inheritance % are always the same, unless the genes, that you work with, have a degree of coupling

The chicken calculators take care of that.
