Help with sexing my young birds

[Noxious]

Hey everyone. I am new to chicken keeping and have unfortunately run into too many roosters and so I really need opinions on what sex these buff orpington and barred rock birds are so I know if I can keep them or not.

Here are my 2 buff orpington chicks, they're about 11 weeks old:

And here is the barred rock. This bird is a funny one because it has mounted and crowed once (a long time ago) and yet it looks very much like a hen (this may be because this was one of two of our very first birds for awhile and had no roosters at the time, so it may have just taken on the role of a rooster as a female). It is approx 6 months old.

Thank you so much for any help guys. Love browsing the BYC so I just thought of asking here.

You have a pair of Orps, and a Black Sexlink cockerel. He is not a BR.

Wow those are beautiful Orps. You have a pair.
The last bird is a cockerel.

My thoughts. They are actually good quality.

They're puffy Buffies, not the skinny excuses you get from the hatchery.
OP, where did you get the Orps?

I got them from a local breeder up the road. I'll be definitely keeping the pair for breeding because they seem to be from a good line

Aw that's a shame the Sexlink is a cockerel. I'll have to be getting rid of him then unfortunately
