I'm Working On a book series I would like to know If Micro Raptors would have hunted like the Utah raptors and how did they hunt if they did not.

They were two very different kinds of raptors.

Utahraptor hunted in packs to bring down large prey, much like their Dromaeosaur cousins.

Weapons
Utahraptor had many extremely dangerous weapons to use in combat. Its first weapon was its brain. Utahraptor was a "master strategist", and had a fairly expanded brain, aproximately as large as that of a modern ratite like a ostrich or an emu, birds fabled for their intelligence. Its second weapon it had were the claws on its hands. It used the claws to slash and rip apart its prey, and also to get to the good stuff once the prey animal had died. Its third combat weapon was its second toe, which was the deadly toe claw. Utahraptor would use its toe claw to stab its prey, possibly in the jugular vein or spine, causing paralysis and/or death. Its teeth in its jaws were also a crucial weapon, used to tear apart and eat a carcass. Its next weapon was crucial in the hunting process. Utahraptor's tail was used for balance when it was bringing down a prey animal, and also when the animal was running.

Diet
Utahraptor's diet wasn't very complicated. They would hunt anything that was available to them. Due to the fact it mostly lived in a semi-arid climate, it probably still had to drink fresh water. It is possible that Utahraptor scavenged when it couldn't find anything else to eat. Since it was one of the largest carnivores of the early Cretaceous, it could probably scare most other predators away from a carcass that it wanted to feed on.

Microraptor was an opportunistic feeder, hunting the most common prey in both arboreal (trees) and aquatic (lakes, rivers) habitats. (Wikipedia) Both bird and fish skeletons have been found inside microraptor specimens.
