Wow that is a lot of yotes, Don't know how true this is, but the more yotes you kill in an area the more pups the alfa female has per litter. If she knows the pack is down, nature takes over and she produces more pups. I have been trapping for about ten years, off and on and think this to be true. Turkeys are the same way. One year we had a big hail storm breaking a lot of the turkey eggs and sure enough the hens were back on the nests laying eggs late.
