I raise chickens for meat and eggs. Some of the eggers get names and are pets, and I spend time with them, but my meat birds do not get named, as they are not pets. I clean their enclosure and care for them, and that's it, because at the end of it they're dinner. They had a good life, and now they are done. I always say a prayer to thank them for their sacrifice, and then I make it quick. Any life I give them, regardless of how short, is 100x better than anything they would have had commercially. If it weren't for my desire to raise meat birds, they wouldn't even have had a life.
If you end up dispatching but can't eat them, your dog or cat would love them. Or your compost heap. Fertilizing the yard is not wasting them. Or you can boil them and feed them back to their flock mates. I'm not kidding - chickens (and I assume quails) are omnivores, and very happy to eat raw and cooked chicken (any meat really). They will also eat feathers, skin, bone meal, etc. They have no qualms at all about it and will descend upon the delicacy with great joy. They need protein in their diets to be healthy, and will happily consume frogs, mice, snakes, insects, fish, and anything they can catch. I generally feed them the leftovers when I roast a chicken once I get all the meat off the carcass.
What some folks do, is go to the store and buy a number of commercially raised chickens/ chicken breasts (or quail would work), then package them the same as the home raised ones, so you can't tell the difference. It helps with the guilt, because you don't KNOW you're eating the chicken you processed. I think the home raised ones taste so much better, and once it looks like the whole chickens sold in the store, the ick/guilt factor is done for me, as then I'm on familiar ground. Once it's plucked and gutted it looks like food, and doesn't bother me much if at all. I know what to do with a whole chicken - been cooking them for years. And once you've done the processing for a while, it gets easier. Because darn they're tasty!!! And so incredibly fresh. So much better than anything I ever bought at the store!
Good luck with it. The first time is hard.
