They prefer and when I say this I mean it COOKED MEAT. Also you are gonna need lots of narcs I used 200-300 narcs and take like 500 marcoberries it helps so much by force feeding it these berries it makes there hunger go down which makes it wanna eat the cooked meat and speeds things up. Fastest way is using kibble plain and simple but if you like me then go for the first option.
The redwoods are now basically a no fly zone, I lost a quetz, and a pter to these bastards. They jump out of the tree, rip you off your mount, and then pin you and your mastercraft armor to the ground and murder you.
