SLW Roos??

[jbh06]

Hey all,
Wondering if anybody could help me out. These 2 birds are making me think they are roos. the other one in the pic by itself i'm not sure. I've never had slw's before. Some of mine have rosecombs and others the single combs. Any help would be great.
Two roos?

pullet or roo?
Thanks

The two in the top picture are both cockerels, and the one in the last picture is a pullet.

So is it the wattles, or the combs, or the feather markings that determine this?

the combs and the wattles in the case of yours but sometimes it can be the color for different breeds
