Ew, eating babbys is so creepy. Do not want.
Although peacocks will kill chicks if annoyed, lol. And peahens will too, the ones that aren't theirs. Peafowl aren't very tolerant of offspring that ain't theirs, I'm afraid. XD
I don't know that grouse do that, to be honest. Well, the males wouldn't even know what a chick looks like, but the females probably don't, since capercaillie chick mortality rate is naturally high anyway, esp. in captivity.
Oh, as for interesting stuff about my form... it can digest pine needles? XD Other birds can digest pine seeds and such, but not pine needles. This is true of most grouse, however, not just wood grouse.
Another general grouse fact... they haven't got spurs like chickens and peacocks. Instead the males use their beaks and wings and hooky feet to cockfight each other, like in
this video. :3
