What do you mean by separated? I keep all my chickens together, if thats what you're asking. Good lacing is just one of the many characteristics of quality wyandottes. I don't know exactly how the blue laced red Wyandottes came to be, but i do know that they get their red color from RIRs.
Hi, here is a pic of my BLR:
She is not by any means show quality. I have her because i like the look of her personally and i think she is attractive, but she is not anywhere near show quality. Her lacing is way too faint and isn't really well defined at all. Selectively breeding through...
I don't have production reds so i don't know much about them, though i know they are very good egg layers. All i know is that "RIR" in the picture has so many faults with the RIR breed standard it shouldn't even be classified as such.
