what passes for lacing is actually edging...it is different...if you pull a feather, you will see that the outside edge is almost clear where lacing is a dark line around the edge...think silver laced Wyandotte...I have seen a lot of blue Ams, but never seen one with true lacing...
There are a few in bantam . Mike Gilbert developed some in bantam . He sold them but they are still being bred . Jerry DeSchmitt of Wi has some I believe . Someone is surely crossing these to large fowl by now . Easier than the Blue Andalusian cross .
