Thanks for your guesses, at least now I know that it's not only me being confused about the gender

. I guess I pick ashtree's answer as this would suit me a little better (even though I'd prefer to keep both, however the partridge is such a sweety while the white one is more of a 'character'). Do you know of pullets with this big a comb? Is it still possible? Also I thought I detected a slight greenish tint to the partridge tail feathers yesterday

.
I guess I really have to wait until they crow to know :/ .
If they start crowing does it happen over night and then they are on full volume every day or does it happen gradually? (sorry for the stupid question, my first chicks so I am really ignorant).
I am just wondering how much time I have to find a new place for them (not allowed roos where I live) should they turn out to be cockerels.
