Your Aloha chicken project sounds like almost exactly what my goals with my Alaskan Super Chicken (working name, lol) goals are, except I have an added emphasis on features that should make the birds extra cold hardy. Tiny combs and wattles (Rose combs, pea combs, cushion combs, etc,) and I have a personal preference for beards and muffs.
I love a rainbow of colors, and a large dual-purpose breed. My foundation stock are five Spangled Orloff pullets, 3 Buff Brahma pullets, and, at this time, a Buff Chantecler cockerel. I may switch to a Red or Partridge Chantecler roo next summer, depending on my results. I think Wyandottes will prove to be a useful breed for me, as well, to achieve the desired cold-hardy comb and a fun mix of colors with dual-purpose utility.
Going back to read the rest of this thread, now!
