Well they are certainly not "Kicking" each other, as the headlines suggest, but it is normal.
Saw the same thing with my twins, the big one was kicking the little one in the head, gently of course.
And yes, the big one is the Male and the little one would be the female......as would be normal in most circumstances. Which means they are Fraternal
twins (2 different eggs), not identical twins (one egg split)...probably an older mother, which is relatively common....
