Black Java vs. Mottled Java & genders please

[GoodLuckCharlie!]

Hi, I have 2 Javas, 1 Black Java and I thought 1 Mottled Java, but someone on another site suggested they are both Black Javas. I was curious of others opinions, and genders pretty please, thanks.

My daughter decided baby chicks are for putting on her back and letting them scratch her back! Funny

Yay thanks! Well, actually, I wouldn't mind if they were roos, but I don't know if they're purebreeds for breeding since I got them from the local feed store. I assumed not, but I contacted the Java Breeders to get their thoughts too. Thanks.
