Recently, I bought Ameraucanna chicks between 1 and 4 days old. 3 of those who remain(always gonna lose some, sadly,) were sold as Lavender/Self-Blue. Now that they're starting the get their feathers, I have concerns. For the most part, they look white so far. But some of the feathers have streaks or splotches of blue or faded black, one more than the other two. Said one had a whole feather that is dark blue, nearly black. I have two Blue Splash EEs, so I'm well aware of what Slash looks like, but I'm HOPING that there was not a mix-up of some sort and that it is only leakage, which I find oddly satisfying. My questions are, a) Do/Can Lavenders start out extremely pale/white and darken with age, and b) Would/Can black leakage look more like blue splash?
