IMO if you cannot haze this animal to leave for example with dogs or electricity you will have to resort to trapping (often they return) a more lethal method. Moms will teach their babies. We have had mountain lions here teach their cubs bad stuff.
Super predators that prey on humans (wolves, bears, lions, jaguars, coyotes etc) are a threat if they are hanging around homes and communites so do consider sometimes living in harmony means removing the habituated animals.
I have riden my horse up on a trail upon many a bear..all have run. I would call those good bears because they respected my presence and showed fear. THey were probably also well fed and not over populated.
Receintly a bear near were we live bit a guy in the butt as it ripped open his tent at a camp ground about 15 miles away. His offence was smelling good. There is no longer any HARMONY when predators are acting this way.
People often blame the victum...but this is not fair. This bear has become habituated to humans and thus was no longer a respectful bear and would probably continue excilating that behavior maybe next time even killing a child. Often time this does nto get reported and then children are put at risk.
So first we need to make sure they do not have a good deal (or meal) when they come near our homes (all we can do is our best being perfect is hard) and second we need to remove (trap and relocate if possible) the habituated animals as all they do is teach their babies to also break into homes, tents, campers, trash etc. We also need to think if their is too much population of the specific species as to the reason they are hanging around. Watching the habituation training of animals....too much gun fire does not haze animals away but habituates them so they do not understand the meaning of the noise...just llke how you can train a horse to be calm to the crack of a auzie whip...habituation and desensitation. Often that is the old and young animals are pressured into human communites for an easy meal due to population expansion or prey decreasing in the area...these animals do not want to go hungry so they prey test to find new or similar foods to eat (chickens are similar to wild turkey maybe easier to catch)...and problems start.
Sometimes even our game and fish people assist these animals in these habituated behaviors...but I will not get on my soap box there as their are many good game and fish people that are not extreme wackos that think it is ok to have wolves around our homes and communities following school children home from the bus stop (yes this is going on in the USA!)
I think many of you already know this even more than I do.
Great pic of the BC in the tree. Wonderful dogs.
it will be intresting to see how you solve your problem. I am sorry for the loss of your chickens. This bobcat is not living in harmon with you is he...
