They lose 1 point of food every 15 seconds, so to time how long until they start starving, multiply their current amount of food by 15 and then divide by 60 twice. This will give you the number of hours left untill the food stat reaches 0.
Equation:
((15 x food)÷60)÷60

With TLC Update 3 out and wyverns are now breedable, I would definitely recommend getting a 190 high base stat breeding pair ready for the future as I don't see why they wouldn't make Rock Drakes breedable as well.

So they made wyvern breedable November 7
So just release TLC update 4 and Have the rock drakes breedable and add tek Rockdrake

Obtaining this creature will require you to enter the tek trench where puprle liquid and the nests of these creatures lay past the bioluminescent chamber, there you must steal an egg and raise in a cold environment feeding it nameless venom you can get by killing nameless

The rock drake trench can be found at 57,56 at the area of the map called grave of the lost. Recommend u bring a glider suit and climbing picks and if u have a good tame to fight the drakes. In the wild they can be invisible and can glide in the wild so watch out also wear a HAZARD SUIT it's needed. Lastly there are a lot of nameless in the area so bring a light source. Good luck and ohh it needs to be cold to hatch so air cons

Their eggs are the opposite of wyverns, they need to be very cold to hatch. It took mine 20 air conditioners to get to the right temp! You feed them Nameless venom when they hatch.

Try 20 AC units. I thought the game was broken just keep going!!

They are really easy to raise. In 10 minutes they lose about 57 food and in 1 hour they lose 343 , also , 1 nameless venom gives 400 food.

The megalosaurus is good for raiding the rock drake trench but it cant jump up the ledges. The spino is better than the mega in every way. The karkinos is a great choice it can jump over the ledges but you will get stuck in mid air and the karkinos cant attack when in mid air, bring a shotgun if using a crab, it will also take forever for you to get back up. The reaper is the best choice in aberration strong as the spino but can jump like karkinos. The absolute best choice is the tek hover skiff.

DO NOT USE 1 POUNT IF FOOD EVERY 15 SECONDS IN YOUR EQUATIONS (for raising rock drakes) I’ve seen many comments that say this but i have tested it and the babies lose 1 point of food every 10 seconds! If you assume it as 15 seconds your baby will likely die!

If you have the ability to go to genesis I highly recommend you tame a bloodstalkers for one of these litteraly 5 minutes ago I got my first Drake egg with a bloodstalke and it was lvl 185. Keep in mind it was official small tribes

Rather than looking at the various tips on food loss per time, start a timer and stop it when 5 food is lost, then divide by 5 for an average. Every rock Drake is different, I raised 4 at same time with different timers.

You have to steal an egg like a wyvern. I used a lot of ziplines and a high level ravager to get down there, used the pick to climb up to an egg and ran. The drakes nearby WILL aggro on you. I got on my ravager and ran away on the ziplines. Make sure you have a hazat syit to protect you since there is radiation down there.

They shouldn’t be in Val because rock drakes are a big part of ab and it would make it virtually useless since reapers are now in gen

Best method for stealing eggs: Tame 2 megalosaurus (opposite gender) and breed them. Your imprinted baby will be the one you ride on. Then, you take your imprinted megalo and the opposite gender for mate boost. Btw each megalo should have at least 14k hp and 320 melee. Use this method for easy first drake.

I used a very effective method but it sounds like a joke, but it works fine: use a gasbag, 20-30 vegatible cakes for gasbag healing and like 10-15 stacks berries for gasbag food and at least 2 hazard suits. You can easily fly down to the spots where the nests are, then fly to the nests, steal the eggs, fly to the entrance of the complex and repeat it. Important: if you want to play safe, then only take the nests on the highest spots, because if you go for the lower spots, it can happen, that an army of drakes stuck you into a nest and your gasbag and you will die. If the cakes are empty, you have to go back to the "non radiation zone", cause after a time without healing the radiation is too much dmg for the gasbag. But this method only works fine, if you a) can control the gasbag and b) the gasbag should have at least 6-10k hp, 2-2,5k stamina and over 100k oxygen. And don't forget to regain stamina and gas every time.

The easiest way to get and egg is to find someone taking a basilisk.

Real men get the eggs alone with climbing picks and glider and kill the mom with their bare hands like men

You can't tame a Rock Drake by knocking it unconscious. You need to find their glowing nesting caverns and steal one of their eggs to hatch your very own Rock Drake.

Manas are prolly the easiest way to get eggs if u breed for a fast one it’s super easy make sure it has a good amount of health tho cus the radiation does get annoying it won’t kill u but you can never be too safe
