HOW would I produce an Line of " Sex Link " NN Bantams ? What Breed would be the most overall Successful. There has to be a way to project Female or Male Chicks By down/hatching Coloring !
You would need have adults w/ a known color / pattern that is sex linked. Barring is one I believe, females chicks being darker and there being a difference is head spot size between male and female. I think the barring would follow though generationally.
The other way I can think of would be w/ the red / silver combo, kev or the other genetic gurus would have a more complete and accurate explanation, but basically you would need adults pure for each color, by gender (ie red females and silver males) their offspring would be sex linked at hatch by color HOWEVER those offspring will not be pure for either color and not be able to have sex linked offspring.
