I tell my kids "Don't worry, we won't eat these chickens while they're little & cute"
For myself, I find it helps to view the meat birds the same way I view the produce I plant in my veg garden. I tend it well right from its start, provide for all needs, protect from predators, prevent disease, admire its growth, and anticipate its wonderful taste at harvest.
Cornish X grow fast & seem more like dinosaurs than chickens. They eat & poop a lot too, you'll be more glad than sad to see them all go. It's only 8-10 weeks until they're grown, so you shouldn't have too much time for making happy memories with them.
And then you get to take them to a processor, like sending them off to get jobs and having them send home groceries. I wish there was a place like that near me, especially at the low prices I hear some folks are paying per bird. There's very little that I would do with a chicken for anyone else for $1.50 apiece, but I would be glad to pay somebody else that price to process my chickens.
I wish you success, start collecting good chicken recipes!
