Ive mixed my barred rock hen with my americauna Roo.It is my understanding that the should make a sex link but i just dont know which one is the hen or which is the roo here are a few picks they are about 4 weeks old..

I think the Roo is at the top and pullet at the bottom??

The cockerels should have some barring on them somewhere in some form from the barred mother.
