Shortstack can inherit Father (Goblin) stats and give birth to Human Girl with this stats.
That will likely be a good way do to things when the game is developed further. Currently, breeding for stats is a waste of time, they are not applied.
I made a save where I did not raise any shortstacks and did not breed for traits and I am currently on day 47 and it's getting boring.
I made some full parties to replace the active ones, but fixing that was a bit time consuming when you get all those half eaten parties.
The easiest way was to make a bunch of melee only parties and 2 archer only parties and drag them in as needed.
My melee breeding rooms are just tons of rooms with melee goblins and women, the most I needed to replace were 28 of them so more than 30 is not needed. Then I have 8 women I breed with 2 archers in case I need to replace them because I were too slow with filling melee goblins or they were sniped. Would have been easier just to have 8 archers on them, too.
I keep them all pregnant and only raise as many as I need, paying attention not to raise any shortstacks.
For the lactation room first I used regular women that were freshly pregnant, once I had sisters I bred them with the MC and used the white haired women, easier to spot.
The attacks can be tricky to keep up with and I had to load a save once because I was sleeping on one, but with the 4 melee 3 archers it's not hard.
Past day 40, it really got boring. Would have been earlier if I hadn't dragged around the archers I think.
