@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...
