Spawn Locations

Eggs On Aberation: The egg spawn is exactly the same as the regular Rock Drake

Eggs On other maps: A female will lay an egg in a nest, it spawns under the female when the dinos come out of the "stasis" state (when she is close enough to a player and the game takes into account his AI).
At this moment a calculation is made if the last attempt exceeds 900s (15min) then she tries to lay an egg (35% chance of success) and the counter reset to zero.
If you wait 2 hours to go see her, it's always a 35% chance, it doesn't add up over time.
Small subtlety if there is already a nest or a structure nearby, she does not lay egg or spawn nest (about 30 meters I have not calculated).

Like the Regular Rock Drake, Small Drake eggs require a very low temperature in order to hatch. A minimum of 20 Air Conditioner inside an enclosed room and depending on the location will be needed to reach the required temperature.

On Aberration: Like Baby Rock Drakes, Baby Small Drakes can be fed with Nameless Venom.

On other maps: Like Wivern you can knock out a female Small Drake and collect Small Drake Venom (5 per females stackable by 10).
