Some say to use a flyer, I say pump some lvls into movement speed, get some custom recipes with 150 stim berries in each cake *to get full stam, eat while running* and you’ll out run them, and they will eventually Aggro something else... or should at least :P *if it makes you feel better, just make a wall, and a single doorframe to run through, it should stop a good few, on the other side of said wall put beds, this way if you die you’ll spawn there. Can be used by anyone, just not the beds, to get eggs easy. Make sure there is some kind of cone to keep them held back for longer. And have more beds farther back, and a small base to put the egg in, use bad eggs for kibble, or custom recipes at the beginning* And once you have the chance fly to said egg bin to pick them up, and bring it back to base to grow some :D. Prepare for old fashion raising... no one has cryopods on official, for this map, good luck hunting. Have fun with mutations too ;)
You can't tame these guys by knocking them out. Instead, you need to steal their fertilised eggs (just like wyverns and rock drakes), hatch them and raise them, just a bit harder than knocking them out. The eggs can, of course, be found in their nests and do be careful while trying to steal one as the Deinonychus is very territorial. Hope this helps :)
Here's how to steal one early game: If you spawn in at chalk hills 3 and spawn next to a pond walk opposite to the pond. There are some nests right there. Snatch one quickly and run off the cliff next to the pond. Be careful and make sure to fall into the water. From there make a left and you should get to a beach area. From there it should be easy to find your base.
Deinonychus eggs can only be gotten like the rock Drake or wyverns, you just steal a fertilized egg from their nest. Normally I would use a snow owl to freeze it while my tribe mate grabs the eggs. Or you can have a gun and a dinosaur with good melee. (The gun to shoot it if it latches on your mount). And kill them and grab the eggs.
For all I know they are only found in the white cliffs in packs. There is a set of ruins with bridges. The nests that I know of are near the bridges guarded by rock elementals as well as the new fluffy raptor
