I have now calculated with the feed:
Super Heron 15x feed = 260
-------------- 30x feed = 16.400
LVL 10 - LVL 15 feed = 80.000
and
Armordillo LVL 10 25x feed = 20.000
LVL 1 - LVL 3 = 65 Evolve 4 hours + LVL 4 - LVL 5 = 350 + 65 = 415
2 Armordillo Baby ever 15x feed 65 x 2 = 130
Who has no capacity for 2 Armordillo has need as much feed: 915
