Hm... how about a pack led by an alpha and their harem? I would recommend a female as the "harem holder/alpha", so the pack numbers don't skyrocket to unmanageable levels too fast, though it's way too satisfying to watch a bunch of nichelings born per day with an alpha male too (I feel way too bad for the other nichelings in that one playthrough of mine tbh, I made them all go into the water near the end because I couldn't handle them all and I started a new game after that)
