I just checked my chicks and I think I see some tufts. The little stinkers hatched on Friday when I was at work so I don't know which egg they came from but I'm sure some hatched out of the Aracauna eggs. I know at least 1 was marked W2. Do I have to worry about the lethal gene now or does it do its damage during incubation? I looked very carefully at the yellow chickies and it looks like one has a tuft on the left side that is a pretty good size and 1 has smallish tufts on both sides. I'm not sure on the others. How do you tell if they're rumpless? Sorry I wasn't as prepared with my research on these! I'm just so pleased I had a successful hatch! THanks!!
