I am going to respectfully disagree with you on that. In my case it has to do with my location.
Sending pictures of my entire operation is nearly impossible. I have several coops and pens covering 5 acres, intermixed with trees and open spaces. Each coop has a covered run. I keep the birds locked up during breeding and hatching season. I allow almost of my birds to free range, free ranging has dangers. I accept that and plan for it.
I have farm equipment, trailers, picnic tables and allow weeds to grow 3 ft tall in areas to give the birds a place to hide. I have so many CD disc's hanging from fishing line across the yard, I need to wear polarized sun glasses to avoid going blind from the welder burns on sunny days.
My problem is the Federal Government. I live on what is left of over a thousand acres of family farm. This is land that has been in my family since the 1870's. I only own 13 acres now. The federal government stole the land from my Dad and Grandpa when I was a senior in High school. I am now not allowed on what should be my land.
When I say stolen, the feds say "eminent domain". We had the misfortune of having 1 1/2 miles of river land with high bluffs overlooking a wide meadow adjacent to 140 acres of a Tamarack swamp. The Tamarack trees are ancient and tall, they make the perfect place for eagle nests. The hard woods that were our pasture and fire wood areas make perfect hawk nesting areas. So we have a huge population of them in the area. There is no other farmer (other than a cousin 3 miles away on more family land who only has cattle).
The federal government turned our farm into part of a huge Wildlife refuge. In their wisdom, they have forbidden the taking of any predator, wolf, coyote, fox, fisher, badger, mink or any other critter than munches on small animals. The wildlife refuge is denuded of any small prey game because of a bulging predator population. There is no other food for the birds of prey than my chickens. I have been on my deck with my dogs and seen a kestrel drive bomb a chick 150 ft away. Sure it left the chick when I screamed at it and ran towards it, but the chick was dead as soon as it hit it. Have you seen the speed they hit at? It is truly amazing. However, as amazing as it was, I lost a bird.
I do not want to lock my birds up all the time, I enjoy them free ranging. I have them free ranging for the peacefulness it. I also have them to help control bugs and mosquitoes. They do a great job at that. There is not much I can do when I am surrounded by 30,700 acres of wildlife refuge and another 5,000 acres of State refuge/park.
I could keep them locked in my Fort Knox like pens, but that is not the way I want to raise them, I would get rid of them before I did that. I do keep them locked until 9-10 am to get me through the worst hours. It helps. But I have lost them in broad daylight. I have used a brush hog to cut the underbrush back in the "wood's surrounding my farmyard. To try and give me a good shot at a 4 leg predator. As much as the Feds hate it they can not stop me from shooting and trapping their pets. However, I am not allowed to do the same to the birds of prey. I have to just suffer the losses to them, much as I have to just suffer the theft of family lands.
Sorry for the long tirade, I felt anything less would not explain why I have such losses.
I should mention I have some "rare heritage" birds I breed. I keep the breeders locked up year round, I have no losses from them. They are just too expensive to give to the BoP's.
Also, to be completely honest not all my predation losses are to birds, irresponsible dog owners that let Fido run free have caused me problems. Those I can take care of with the SSS method. I still get some from 4 legged predators that have no small rodents to eat in the refuge. When they have young they are desperate for food for them. I have the only oasis of prey for them, not only in my chickens but the rabbits, squirrels and chipmunks that steal my chicken feed. I try to control them, but I would hate to kill them all off to.
So I cause some of my own problems do to the lifestyle I live and want my birds to live.
I hope that explains it all. Have a good one!
