Crowing
Also, a lot of splash chicks are often white/yellow with light grey down their backs as day old chicks, rather than all yellow like a white chick.Blue (my namesake Brahma rooster) was blue as a chick, pale blue for a Brahma but blue (hence the name). He is actually splash, but the splash parts didn’t show until about 8-10 weeks. He is a darker splash than all my splash hens (unrelated to him). Splash is quite a varied phenotype, it seems yours is similar to his, quite dark, the base being medium grey rather than white/light grey.
