To get an egg you only need an Iguanodon and a Tribemate. The Deinos will aggro in the rider and dismount him so you can take the eg change the sed and run. Youre tribemate shouldent have good stuff cause he will die.
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 :)
#1. Ride your flying mount and scout for deinos nests at chalk zone biome.
#2. Stop at high ground and wait for the parent deinos to chase something away from nest. Or use your Argentavis to carry and drop nearby Ankylo or Doedicurus as a bait to distract the guarding deinos. (Be smart! Wait for the perfect opportunity to do step #3)
#3. Approach the egg using your flying mount quickly!
#4. Jump out near the egg -> TAKE THE EGG QUICKLY -> jump in and fly away ASAP! (This must be done in less than 5sec!)
#5. Make a 4x4 thatch/any foundation with closed wall, roof and a door entrance.
#6. Place 10 standing torches inside. (Add more if the egg says "too cold")
#7. Drop the egg/s then light up the torches.
#8. Wait for the incubation to reach 0%.

Well you use a pter and oviraptor because you don’t need to get off and speed things up. You set the ovi in wandering and lure all the deinonychus away from their nests and the ovi picks up all the eggs. When you are sure they are all gone, you go back and help the ovi get all the eggs (oh and pump weight into your pter as well) and pick up the oviraptor and fly away to your base.
