Any ideas what breed this could be?

So, I have a beautiful Rhode Island Red hen that hatched two beautiful chicks about a week ago. One of which looks like a barred rock chick which makes sense since my dominant roo is a giant barred rock. The second chick is the one I’m wondering about. It’s a yellow cutie with black/brown stripes. A couple days ago I caught the RIR sitting on my ducks nest taking care of the eggs while the duck was gone! This now makes me wonder if this chick is possibly another one of my hens’ chick. I have an isa Brown, Black sexlink, a white hen I think it starts with a M, and an Ayam cemani besides the RIR. Any ideas?
