The chicks are white with random black dots, not penguin marked. I have some younger ones I can take pictures of if that would help any. Generally the more black they are showing at hatch, the faster they get the black in, or that's what I've noticed so far. That one there hatched white with a black splotch on its back and back of the head, and its wing feathers came in mostly white with one or two black and then the others came in like this. Its hatchmate, however, hatched all white with just a black dot on the head. All its wing feathers came in white, and it got its black slower, but now it looks almost exactly like that one, only a bit more white. I'm seeing the same thing happen in the two younger ones I have too. Let me see if I can dig up pictures of the parents. I didn't create this color; I just happened to spot them and loved them and ordered eggs from the breeder who, I think, may have created it, so I have no clue where the color first came from. So far I haven't hatched any all white chicks. All of them have black eventually. In fact, the original parents that I don't own, and those I can post pictures of if that would help, had way more black than I liked, so I've been trying for a bit more white. So far, I think I'm succeeding.
Maransfarmer, I do hope to have extra eggs in the spring
