We have tons of coyotes in the Carolinas. They are bigger and bushier than the coyotes I knew in New Mexico. They are all over the place. They are very adaptable. They eat roadkill and will easily take a young deer. Some claim they often eat the fawn as it is being born and then eat the placenta. They usually hunt alone for small critters but will join together in a pack for larger game. I love them, but I will shoot them.
The one I shot weighed about 45 pounds. Good ole 30.06 takes care of them every time.
I've seen solos run deer year around.
I am more worried about feral hogs and bear on the ranch though.
(Hogs do alot of damage)
Had a bear pop up over a ridge on me once- scary.
