What have you found to be most effective in repelling predators?
What methods have you found to be useless.
Curious about all predators but main issues here are with foxes and owls.
Following is based on direct observations. I can go months or years between sightings on property then they can come in very regularly for a while.
Red Fox
Hunts around the clock and appears to have an established route that consistent patrols
You can smell even when they just pass through
Will hunt with you present once it gets on the trail of a victim which can get into trouble if you have dogs
Does not respect human urine
Does not respect dog urine
May respect Coyote urine
Will not visit when Coyote pack nearby
Can be beat by well positioned hotwires
Can be beat with electrified poultry netting
Good hard chase by a dog will keep it away for months
Dogs can catch and kill them more often than you think possible
Can run fast but not faster than a dog in a straight line. Will use fences and tight turns to evade dog but two smart dog can defeat those options
Cannot out run a dog when carrying even a 3-lb chicken
May follow Great Horned Owl that knocks chickens off roost to go after birds owl ignore or even scavenge (in fall both can come in a single night with fox only minutes behind owl)
Has a hard time killing larger birds which can get into trouble if you have dogs
My games chickens as adults are almost immune to these guys except when defending offspring.
Will work pen perimters to worry a chicken into corner or edge where it will pull bird through so I will move pens together when fox working area
Digs but not when dogs present
Has yet to chew through wire like Raccoons, Oppossums and even domestic dogs are prone to do
Not all Red Foxes go after chickens. A few years back we had one that hunted for rodents within site of free-range chickens without incident. Fox from other direction not friends with first would.
Grey Fox
I have almost not experience with these although dogs did get into one a year or so ago when persimmons in fruit
Does not range as much as Red Fox
Great Horned Owl
Here comes first for rodents / rabbits with chickens being targets of opportunity
Eats head and neck plus able to do so within a couple of minutes
Will start with a 4.5-lb live weight chicken with 3 or four nights of repeated meals before small enough to carry off
Can carry at most about 2 lbs and must drag carcass in to tree to launch.
Drives larger targets off roost and grapples them on ground, often drives multiple from roost then picks one
Somehow it drives victims from perch without actually contacting them
Will go after adults but selectively harvest smaller chickens and will even pull chicks from under wings of hens.
Very predictable in terms of when visits each night.
Will follow me around as I do chores in near dark conditions
Will come in quickly when chickens disturbed
Will stare at dogs only 10 feet below but will fly when I am also present
Difficult to remove when entangled in netting (bites and strikes with talons)
Will hunt from ground
Does not respect scarecrows
Can be stopped with bird netting and seems to not even want to walk near it
Can bluff most dogs when on ground, except Scoob
Close call with dog does scare them off for weeks
Can reach chickens within 6" of a 2 x 4 welded wire panel but stopped by chicken wire unless chicken roosting tight against it
Hard to stop with hotwire actually attached to coop
Not real smart about very clean windows
Barred Owl
Targets chicks and I have never had one go after adults
Seems to come only on very dark nights when GHO's not around.
During winter eruptions of Short-eared Owls the Barred owls get stupid taking more risks hunting
