Feeding 12 hybrids might take a bit. Or not. We’ll see what happens
Not doing that. Yet. In any event, will feeding super-hybrids count?
Of course I already know that you won’t be doing these missions!
In my opinion they will increase the range of the level (see the spaces of Isla Sorna still not unlockable) and these missions will be useful for you when that happens!
And the answer is. Feeding super-hybrids (or at least Diplosuchus) does NOT count
