when breeding blue slate with anything, it has a 50/50 chance of comming out black. so they could very well be blue slate x bronze. I have that cross and they look almost like blue slates when they mature, they just have a bit of barring
Remember, blue slate produces 3 colors (just like blue in chickens)... blue, black and self blue (sometimes called lavender or splash)
