First, drop your FERTILIZED eggs on the ground, get on your argy, or anything else of yours that flies, and hover above them while they eat. No stress, no problems. One of the easiest tames ever. Note: there will be an interval between each feeding.
As for the eating of eggs after taming: place down a couple of troughs w/ eggs or put them in cryo pods that then go in a cryo fridge.
You tame them by droping ferti eggs from your inv on the ground. You need to do so when the snake is not aggroed, so sit on a rex or smthing it wont attack. Be sure to drop them from your inventory, not from dino ones, that will make it bugged, it wont eat. To a lvl 20 Rex egg gives 29% on 2x event, bronto 26.7% and giga and wyvern the same, looks like all the big eggs give approxymately the same amount.. so dont waste the best you have ? If they get aggroed on you just run away and return, taming wont drop. Happy taming!
Please note!. After tamed, THEY ARE EAT AN UNFERTILEZED EGG OR WILD EGG TOO!!, so dont spending your fertilezed egg for them. Find a wild egg, or make a dodo egg farm. And good news their food consumption are so little. I made a tried. So i put 10 dodo wild eggs on their inventory, and it still 7 eggs lefted after 15 days tamed (in game). Then I tried to put a bigger egg (1 spino wild egg), and they ate it when they are really-really starving (when their food bar is almost empty, maybe more less 10% lefted) it took 17 days to eat 1 spino egg, from full bar to almost empty bar.
Note: dont worry if they didnt eat your big egg. Becausez they are wait untill their food points is decreased as match with the many of the egg will fill. They know how many the egg will fill their food points, thats why they didnt eat it quickly
If u are in ark mobile ( like me ) and u want to get titnboa eggs make a small room without a floor pick a female with an argy and drop it in the room and get the eggs (sorry if there was any grammar mistakes)
-Build a trap wooden, 3x3, 3 walls high (with entrance ramps if pve) just out side of swamp.
-Drop or lure Titanoboa inside.
-Fly up untill out of render distance to stop agro
-Fly back down, hover above (not too close)
-Drop eggs 2 - 3 at a time from your inventory not tames.
