@angry rooster I've heard the same thing, shootin up the coyote population results in them breeding more (wish that worked for deer). We'll keep culling them hard and hope for the best. If there is any big cats or wolves in the area it's rumored the state introduced them to deal with coyote population (of course they deny it). Really don't want anymore large predators here, bears are bad enough, don't dare let the kids play outside by themselves as is.
Scientists say we'd have to knock out 70% of the their population (coyotes) every yr just to keep them in 'check'.
You mentioned those flashing red lights, I just recently read about them, I thought animals couldn't see red??
Even with all the predators here (just recently got a fisher population, enough to open a trapping season on them) they have left our coops alone. Outside dogs keep them away I think.
Skunk and opossum are the only only ones I've had to deal with besides hawks. Skunk made it into run at night, I think after food left in there. I almost dispatched it, but I was scared, in and outside googling if they spray shot between eyes. Luckily it decided to leave on it's own. Buttoned up run.
Left coop house door open one night, had a opossum in there, it didn't leave on it's own...
And there was a hunting magazine that had a article about what coyotes can see and they can see red but what there spectrum looks like is grays and yellows and green it's kinda like how they add colour to the old movies the info is there but they have to work at it to differentiate between the colours an there thing that was cool about the article is they talked-about the different calls they make like if you shoot one you can make a death cry and call in more or stop the one that you missed in its tracks
On the bear thing I hope they leave you alone and the only thing that I know that works for them is electric fencing
