Botulism, e-coli and anthrax have been part of the ecosystem for many years also. But, I don't want them intruding into my life either. Not being mean spirited but, when people use terminology like ecosystem or, live-and-let-live, we should remember that the survival-of-the-fittest doctrine is purely THE WAY of nature or, the ecosystem if you will. I believe in taking any legal means to a prevent a killer from killing your stock.
No one hardly ever quotes some "humane" doctrine when referring to ants, rats or moles. We tend to take the "righteous route" when it comes to an animal as stately and beautiful as a hawk or, as cute-n-cuddly as a raccoon or fox. Once a person witnesses how absolutely horrible the death of a chicken is by fox, raccoon or by hawk, they usually overcome any sentimental feelings about these killers. These three literally tear their victims apart piece-by-piece. It takes a while for them to finally die, screaming the whole while. Neighbors show up at my house all the time looking for trapping or killing advice, with a new-found disdain for predators, after seeing their lovely chickens, littering the yard, killed just for the joy of killing.
I have made some small pavilion-like shelters, open on all 4 sides, about 24-inches off the ground, made of netting for my chickens to run under when under aerial attack. I pull palm fronds into strips and weave it through the webbing to hide the chickens from view and to give the chickens a sense of being concealed. I stake them down ridiculously strong because of their kite-like design. At the first alarm call from the rooster, the others make a beeline for the shelters! My wife wants to plant some small shrubs/vegetable greens around the shelters to help soften the effect. The shrubs should also help keep the hawks from walking into the shelters on foot.
I don't have skunks here but, did have them where I grew up. Skunks were one of those animals that would kill dozens of birds and eat only the heads of maybe 2 or 3 of them.
