I'm VERY aware of all the different flaws and contrasts I'd run across if I did Marans. . . But right now, aside from SL and WCB Polish - They're the closest I can think to "proper" breeding. The rest of my birds wouldn't help with anything.
gretchen: I've never shown Polish before, and only bred WCB for one generation. I don't even know what Silver Laced, gentically, are (but I would love to hear from someone on that) So really, not too much experience there. I just listen around forums with what other people experience. I don't actually have too much experience with breeding Polish for the simple fact that non-hatchery birds, especially LF, are SO hard to come across in my experience. (at least, the colors I want) Crested Polish have always been a favorite of mine, but since I almost never find anyone with LF birds for sale, I've been sticking with breeds like Araucanas, Ameraucanas, and Marans.
josh44: Standard/LF. I'm just not really a bantam person.
One thing I'll say now that I'm very impressed on my boys with is that they never had such gleaming, solid white chests like everyone else youngins I've seen.
