Men

The Men would be the best ones to go for, your tribe has used them as breeding stock in the past after all.

Of course before you can think about that you need to find a place to set up a new Burrow. This part of the world is colder than the place you had been living in before, the hills rise up into sheer cliffs all over the place and there seems to be little in the way of edible plants.

It is not completely inhospitable, there is a river that seems to teem with fish and there are plenty rabbits and other small game to hunt. However you find it hard to find ground that is good for digging. The ground is so thick with roots that it is hopeless to try and dig out a burrow, instead you need to try and find some place else to live.

The question is if you want to go looking for a cave or try to pull something together above ground, there are plenty of fallen trees and other litter on the ground after all.
