Never done it but I would just like to know where you got your White Rock hens that you used to make the Sexlinks. There are some strains of white Rocks that wont make sexlinks and I usually tell people in general to just stay away from using white rocks for sexlinks, but if you have found a line that does have the neccessary genes, can you please tell me where you got them if you know their origin ?
Also if you could get some pics and post them in the Sexlink thread or make your own post about them in the Breeds/ Genetics section, that would be great.
