dinosaur refuses to eat/drink

[Promises]

a handful of raptors ive released refuse to eat/drink.
despite the fact that they have a pretty sizeable pond in their enclosure.
aswell as i put literally a feeder like every 15feet (theres about 12 of em in the enclosure)
and they still refuse to eat/drink to the point where they will die if i dont constantly have ranger teams going out to heal them
