A sexlink is a cross I think it's a rir and a barred rock not sure tho . But they call them sex links cause at hatch you can tell which one's are male's and which one's are females. The females have a white spot on their head and the males' do not , if I remember right. I have all kinds and I will say my rir's lay everday and so do my silver laced wyondott's but my barred rocks do also so I don't know which one's you fancy but all these are good egg layers although I will say my rir's egg's are not as big as my wyondott's eggs. I have an easter egger and she lay's four day's out of the week but she is eight yr's old too. I also have a anocona and she lays a very small white egg but she just started laying . She is kinda like a leghorn but she isn't as friendly as the other breeds. I guess it's just what you want cause their is alot of good egglayers out their that are really nice breeds .
