Getting eggs for these on Valguero super easy for low levels:

Step 1: spawn in the chalk hills area near the end of the lake and there should be an abundance of lymantria

Step 2: speed run a lymantria saddle and then easily tame a lymantria with a bola and a bow(no crossbow needed)

Step 3: distract the deinonychus when you find a nest, lure them away and use the fart attack on lymantria, quickly hurry back to the nest and steal the egg, you must be very quick, even though the Lymantria can slow down the deinonychus

Step 4: hatch all the eggs, use about 15 standing torches lined up like this in rows of 5: _

Step 5: breed these for health, stamina, weight, and melee as these are the most important stats for deinonychus

Step 6: make packs of 5 and go kill pretty much anything with them, they can easily kill tamed gigas if mutated and they are also great as an all-around mount for PVE and PVP, they are insanely fast travelers, can be boss killers, are are overall super useful because of their fall damage negation, high attack, bleed damage, fast speed, charge jump, and somewhat of a climb ability.
