Help with Gender - 8 week old Buff Orpingtons & Black Australorps

My chicks just turned 8 weeks old on Monday. I'm already convinced one of my Speckled Sussex "pullets" is actually growing up to be a roo. Now I'm starting to doubt some of my other chicks. I can try to take better pics tomorrow if needed. These guys are not easy to photograph by myself. LOL

Both chicks of each breed are very similar in size and development to each other. Unlike my Speckled Sussex which was my first red flag early on. I would appreciate any opinions. I've already read through a ton of sexing threads and feel pretty confident in my guesses for my other breeds. My Black Australorps have me the most concerned. Thanks everyone.

All pullets.

They all look like pullets to me, too.

Big sigh of relief. I wasn't planning on any roosters and am positive Fannie my SS is now Frankie. LOL I will try to keep him as long as he doesn't disturb my good neighbors. I want to be a respectful neighbor. I hate to part with any of them as I'm so attached and they're all just the friendliest little chickens I've ever been around. I honestly thought the Australorps would be my favorites but admit the Barred Rocks have stolen that spot. They both think they're a cross between a parrot and a puppy. LOL

I really enjoy reading through this site and appreciate the speedy replies. Thank you!
