I have recently gone through the waiting and the confirmation of rooster characteristics that, especially in the easter eggers, was a wait for saddle feathers to be sure. The ee's that turned out to be roos had much more red in their rose comb, redder and wider than the ee pullet in your picture. I think they are all pullets. Buff Orpington pullets are a buttery yellow with white legs. I had one that looked like it had pale yellow legs but they are white now.
