hatching a black moa

does anybody know if you have to complete sorrows furnace to hatch the black moa chick, or can i just party with someone with "The Final Assult."

EDIT: sorry, i just realized i posted in the wrong forum. move if you wish.

You can party with someone that has final assault.

I can say this for certain as 1 of my toons had never been to the war camp even and after running there got his Moa.
