We feed our culls to the dogs. I did it last night. (First one I've culled, but it's always been our plan.)
Dogs have to eat too. I'm honestly quite freaked out by Cornish X from the grocery store and hate feeding Tyson chicken to my dogs. I love my dogs but I can't afford anything better than that. It's actually part of the reason I started raising birds on a larger scale.
I tell people about it not trying to freak them out, but honestly people are way too removed from what they eat. I would imagine someone interested in owning their own chickens (either for meat or eggs) would understand where meat, including dog food, comes from.
When people react poorly to the news that we process our birds, or feed them to the dogs, I ask if they're vegan - I'm 100% serious because I'm always trying to find more vegans. It's hard being the only vegan chicken farmer I know. Of course, they never are, so I ask why they are okay with eating a 7 week old chicken that would have died of a heart attack before it could breed, that may never have seen sunlight, simply because it came from the grocery store, but it's sick of me to use a 7 week old bird to feed my dog. What do they think is IN dog food?
Then you have the people on the opposite end who immediately upon learning I have chickens ask if we eat them, or what we do when they die. When I told my dad about some of our birds being killed by predators he asked what we were having for dinner. Honestly that's disrespectful (trying to offend someone on purpose by making jokes about their animals.) I just responded "Well we would have fed them to the dogs but I don't know how long they were dead, might have some bacteria or parasites, it's not worth it." And of course he's grossed out. How is it okay to make a joke about me eating my birds but actually knowing that the dog is eating it is gross?
Not trying to be rude to you or your wife, please don't take this the wrong way. Sometimes I feel like I was the only one there that day when we learned that some animals are carnivores, and meat from the grocery store is animals, because it seems almost no one else gets it - it's freaky to feed a dead chicken to a dog, but it's okay to feed ground up dead chicken when it's mixed with ground up corn, and dried into a pellet. My husband started describing to my MIL last night about us processing the chicken, and she freaked out. But she eats meat! I don't eat meat, or any animal products, but I understand that my dogs are carnivores, and I'd rather feed them animals that I know were raised humanely and processed humanely over animals I don't know where they came from and have a high probability that I don't agree with how they were raised and butchered. Yet I am viewed as weird by 95% of people. I guess I'd rather be weird.
