the bigger one does the two-syllable calling, has a box shaped frame, and much much blockier head than the other one. the slightly smaller one has a more triangular, smaller head. I have not heard her buckwheat yet though.
I do not know, perhaps they could both be male.
My 8 week old keets just fought yesterday and the other keet's head started to bleed a little bit. then the losing keet crouched down and the fight was over.
Are my keets both male? I thought one was a female since one is a little smaller than the other.
