Shredded or not, the males are the lucky ones.
If I had chickens, I wouldn't kill the males. They would just be encouraged to go 'feral'. They'd be marginally subsidised, and their feathers would be used for art and accessories during molting season. I used to make hair ties, wall decorations, belt loop drapings, etc. . . My stuff was pretty impressive and beautiful. I used duck feathers, goose feathers, and if I found a hawk feather, that would specifically go tto someone with First Nations blood. I gave them all away, though one I asked the lady to make a donation of choice to a First Nations charity. She sent 'em five bucks.
For the umpteenth time, I'm glad I no longer eat chickens. Though I can't say I've given eggs up, I haven't bought any since the chicken flu started. Despite never formerly declaring I'll never buy another egg, it might go that way. On the other hand, I know some people with backyard chickens three blocks away, and I could ask if I could buy theirs next time I see one of them; but I probably won't.
