To be honest, and quite frank, with you about it, your not going to find any Bantam Silver Laced Cochins that look like the Whites, Blacks, etc that you see at a show, or see people posting pictures of. The variety is pretty hard to find, and that is why several breeders are outcrossing to Black, White, and Columbian to better type on them. Most people that have them and that sale eggs or birds, are not going to be anywhere near close to what type should be for a Cochin. So to be honest, either way you go, your probably going to get about the same result. From a hatchery you will get numbers, and may get lucky with a couple that are really nice, and I wish you the best of luck if you choose to do so, wish more people were interested in the SL Cochin Btms. And also remember, even if you dont get a bird that looks like a White or Black, doesnt mean you cant breed for that and help the variety become less rare.
