Oh I have 1 silver laced Wyandotte and I just love her! If you do ever decide to breed them, let me know. I'm in a similar situation. I have LOTS of pure breds, but I let the free range together for the most part. I do keep my bantam Cochins alone. I have to figure something out there as well tho, because I have a Frizzled Bantam Cochin roo and 1 Frizzled and one Smooth Bantam Cochin hens. I want to hatch the eggs from the smooth Cochin, but not the Frizzle since my roo is a Frizzle too. They say that leads to feather issues in the offspring. So I either need to learn to distinguish between their eggs or put them in a different pen. Let me know what you decide down the road.
