I searched splash rosecombs and all those birds look similar to Sebrights, not the round little hen Matthew posted. From the size of the chicks, I'd guess she's a bantam of some kind.

That is the same hen with the 5 chicks in Grit. Our luck she is a barnyard classic
I saw a hen that looked EXACTLY like that in Grit magazine. I want one too, but don't know what she is!!! I thought CA Whites were all white, no spots?
