Congrats on getting some wolves would be interested in how, guessing shot but called in, off a kill etc etc.
I am in no way taking away from what you have done but jut saying it is not alwas the best to take out the alphas if you have a choice especially around breeding season, thats if you didnt get the whole pack, for this opens up the door for the chance of more pairs to breed and may have twice as many pups next year.
