RE: Coyote vs 3.5" #5 Hevi Shot
Be glad you got the female.
I read an article a few years ago saying thet coyotes are long-term, if not life-mates. The female tends the pups and the male hunts for both of them, and later, the pups too. The female will go a short ways for a pretty sure meal. If you kill the male first, that forces the female to hunt AND tend the pups, so she goes after easier game -- like calves. That's when they get to be a nuisance.
I wouldn't worry about those pups. They would only grow up to hunt together as a family group. In such numbers, they WILL bring down deer. I've watched them do it! AND they're prety tough on poults. If you can find the den, or if you think you know the area, spread out some meat scraps upwind, and then hide and wait. You might be able to rid yourself of a problem that would plague you next year.
According to that article, (and it may have been in a Mississippi MDWFP publication) those pups were probably born in February, which means they are old enough to wean and survive if Papa can provide meat. Have no mercy! Go on back and keep an eye out for Papa. He's going to have to keep on the move to provide that much meat.
IMO you did good getting rid of that pest. Good luck on the rest of your season!
