Geez! I'm trying to catch up and you all are adding pages as I go!! I would have never got to the end if I didn't just start skimming....
I once had a problem culling a duck... I took it to my vet who did me the favor of doing it like a dog or cat. Other than that, I put them down myself. I find it is harder to put a animal down for a injury or disfigurment than for anything else. But fact of the matter is, they wouldn't have a quality life and eventually would be taken by preditors or starve or get trampled ect.
There is 2 problems at work here (accross the board)
1. people put human attributes to animals... and let me clearify that I'm not saying they are not worthy of respect
2. people are out of touch of where their food comes from
I'm not saying butchering is my favorite thing (because it's far from it) but I know that I eat a chicken in every meal (I'm a chicken nut duh). It can be my chicken that I knew had a nice day in the grass until the last moment, or it can be a chicken who lived in inches of filth in a poorly ventilated chicken house, crammed with thousands of others... including the dead... and then picked up and literally slammed and thrown into cages where their legs and wings get broken (you seen it when you eat KFC and the bone was broke and the meat stained red.... that was when they were alive) and then put on a truck where even more sufficate from the lack of air just from the pure number of chickens... then taken to the conveyor belt I previously mentioned.
You want motivation to eat your own and feeding useless roos not enough? Watch a factory farm video.
As for dead animals... if they JUST died, what's the problem? If they are gross already, then wear gloves. Personally, I'm the type to pick it up and inspect it. Found a frog dead at work under the cardboard. I work in a factor with nasty chemicals and I wanted to see if the chemicals did it or if he got stomped or what. Plus I wanted to see what kind of frog it was (I am a frog nut too) Point is, I picked the dead frog up and held it to me face trying to investigate. LOL!
