Not sure what this is- roo or hen and WPR or WLH?

Just rescued some chickens. Supposed to be hens but I am not so sure. They are either white Plymouth rock or white leghorn. One is most definitely a hen but the other one has a different body and bigger comb and waddle. Nervous it is a roo bc we just adopted out our RIR roosters that were supposed to be female. Any thoughts on breed or gender? Supposedly they are 3-4 months old. It is the one in the foreground that I am concerned with. Thanks!

I think that they're White Rocks because they have red earlobes, white leghorns have white earlobes.

They are White Plymouth Rocks because they have red earlobes, whereas Leghorns would have white earlobes.
