I thought the splash chicks were a silvery white then got their splashed gradually? The reason I ask is I got some eggs from someone and hatched them. This person was recommended to me and the pics of the adult birds were nice. Now that the chicks are feathering out I have a whitish one that has a yellowish beak? The other two have what I believe is black starting to come in on their hackles, wings and tails. I pulled a hard short feather out from ones foot and I don't know where it came from. These are little birds in a brooder. The feather didn't seem to be attached just kinda stuck on its foot. I do have a cuckoo and a blue in there with the whites. No hard feathers though. These birds have always had an odd cast to them. I have always bred white to white and have never had whites have black in them. They hatch yellow and go to white. In the light..they could be splash. Don't know. The last one is the white with the yellow beak. The black doesn't show up very well. It is splotchy. These chicks are still pretty young.
