If it really is a black star pullet, it would have had all black head with no spot if I remember right. It looks to be about 3 weeks old so it's too young to tell.
Yes, as adults, the males will be barred, so if your pullet grows out with barring, you'll have a roo. As chicks, the barred boys look like baby barred rocks with a white head spot.
Sorry if I'm being stupid, please bear with me I'm new at this. So are these really even black stars? I picked out the chick in the second pic because I liked that her body was black and her head was reddish brown. Thanks for the help
Here's a pic of the same chick that shows the coloring a little better.
