Okay, here's a couple of fun pics. These are "solid" Alohas that that show color - in the most minimal way!
Check out this hen - Cheeto's daughter! Looks solid - but see the one tiny white spot on her tail? If bred to something with spots, like a pure Sussex rooster, she should throw a TON of spotted chicks! What a lovely hen, she should make some great mottled chicks this fall.
Below: And here is another! Hope it is a hen, but too early to tell. See the ONE little white feather?
That is the sort of tiny spot of white that I found on Cheeto when he was about four months old. It was under his folded wing. I never found it again, but it gave me a clue that his babies would probably show spotting, even though the odds were only 25% that he carried the gene.
For anyone starting their own program using Sussex crosses to start, keep an eye out for little clues like this. I crossed an Ameraucana hen with a 1/2 Sussex, 1/2 Exchequer Leghorn rooster, and got a solid gray hen with one little white wing feather. Aside from that one feather, she was solid all over. When crossed back to an Aloha rooster, "Vanilla" she gave me the most fabulous big blue and white mottled hens! Super colorful. So the random small white feather seems to be a very good sign.
