Gender?? 2 week old chicks

[Leo.76]

Hello y'all. So, I need helping identifying if my chicks are roos or pullets. They are mixed, not sure what breeds though. Their dad was a red rooster. I incubated these eggs as a predetor took my whole flock!!! These were eggs my dad's hens had left.
Anyways, here are some pics of all 7 chicks. 2 chicks look very similar btw.

Roo early but if you go by tail development you have at least 2 pulleys but that method is not 100 percent reliable

Too early. Wait till 8-10 weeks

They're adorable chicks, but I definitely have to agree with the other people in this thread. 2 weeks is way too young for any defining sex characteristics to develop. Wait a few more weeks and try again!
