I am all for the original wild style sumatras. The blacks we have and even the duns are more wild like than the domestic, frumpy blues. The sad thing about the araucana crosses is that a blue araucana x sumatra looks more like a sumatra than many of the show strains I've seen. I have never made the cross but it has crossed my mind from time to time. Also, look at the bantam sumatras, they had rose comb bantams, OEGB, and heaven only knows what else mixed in which is why they look so domestic. If I had to choose, I would take an araucana x sumatra over any of the really long tailed, soft feathered show strains that are out there these days but that's just my opinion. The araucana crosses would at least be more feral like and good farm birds
