The most effective fox medicine I am aware of is a few good foot hold traps. As the photo below shows there is no shortage of foxes. A dog is OK but if it chases the fox off your property the dog may run afoul of an Automobile.
I know of no jurisdiction other than maybe California were it is...
The white leghorn looking hen may have been killed by one predator then the carcass was scavenged by a separate predator. Question, is there a secure roof or top on this run? The likely hood of a dog jumping the fence makes me think that other varmints can also gain access to your birds from...
I find it unlikely that a poisonous no-shoulders reptile would be gallivanting around Rural Oklahoma at this time of year, but stranger things has happened.
I am sorry for your loss.
Predation can happen in a New York minute as your tail proves.
Keeping chickens unfortunately requires constant vigilance.
You acted correctly, remember that even Fort Knox has armed guards.
Take a comfy folding chair and spend a few hours in the dark listing to your poultry sleep. Chickens seldom sleep silently. An owl can catch mice in total darkness using only the owl's sense of hearing. Chickens are always squabbling and jockeying with each other for a better sleeping...
You have an owl taking your chickens. Owls have eyes to die for and ears to match their eyes. Not only can an owl see them but so can hawks. A mink can surely slip between the stay wires (the vertical wires) on your fence.
I am unsure about the breed of chicken you keep but I would be...
The first thing that a hawk does after capturing a meal is to peel the fur or feathers off it's prize, sort of like you or I would peel an orange, to get to the good parts.
Once a predator of any kind is inside the run, the wire only makes it easier for a predator to kill your birds, because...
The feathers left behind is an example of a classic hawk attack. A 5 week old White Leghorn can be spirited away lock stock and body by all three of the "chicken" hawk species, especially after the victim is mostly de-feathered which drastically reduces air resistance
Up to about 50 years ago no one lost very many chickens because they were free range. But it was a different world back then. Any chicken eating predator had to run a gauntlet of buck shot, bird shot, watch dogs, and steel traps to just get within hearing distance of a chicken. Now-a-day the...
