The idea behind this forum is what is the best thing to help your chickens. Just blowing the coons away is the best thing to do if you want your birds to live long, live well, and prosper. Any thing else is just raising chickens to serve as blood sacrifices to the raccoon god.
The principle behind ALL forums is the discuss options available for the task at hand. Killing an animal that's only doing what it was created to do,
survive, isn't the only option. There are plenty so why not discuss them all? There are some that are very key, like security.
Common sense tells me that if a person has the option of providing a secure environment for their flock then there's absolutely no reason to kill foraging animals unless they just like to kill things. If you let your birds free range unattended then you're asking for trouble. I did and I ended up loosing 5 birds total, four of them expensive French Copper Marans to the neighbors dog and one to a red-tailed hawk. The neighbor replaced the Marans and I replaced the one killed by the hawk. I could legally have killed the dog but why kill a dog that knows no better because of ignorant people that allow the dog to roam freely?
Is your coop secure? Does it have adequate welded wire over the doors and windows? Can the doors and windows be closed tightly and locked at night? Does one go out at sunset and lock the birds in their coop or do they wait hours after sunset because they're gone or enjoying a movie on TV? Is the run enclosed? Is the floor able to keep burrowing animals out, like dogs, coons, coyotes, big cats, etc.? Are the birds allowed to free range unsupervised? I know we don't always have time to be out there during the day but if you aren't and you lose birds, that's fault of the individual that allows it. Famers that allow chickens to free range know they're going to lose birds. It's a part of life.
My grandma, who passed almost 30 years ago. raised chickens and even her birds were not allowed to free range but they had a large pen. That's something that I learned from her. When my birds started disappearing, I looked for an answer and that was a pen around the coop and run that allowed them to free range in the safety of a large 100 foot by 40 foot pen. I came home the other night to a coon trying to get into the pen. It was unsuccessful and even if it did, it would never get into my coop because I built it that way. The pen is large enough and my flock of 13 birds small enough that there's plenty growing inside the pen and this spring they will have their own garden. I have 60# monofilament line running across the pen and haven't had hawk problems since. I never really had hawk problems in the pen anyway. They were a problem when the birds were free ranging.
Bottom line is that there are plenty of options, George. If you're option is killing them then that's fine. Just know that it's not the only option and it's not the only humane option, as you put it.
