In what world are you cutting bread in the same place where birds are freely flying around. Like, is this supposed to go outside, or inside? Let's talk about outside. I guess I just walk my bread outside to the bird feeder and start cutting my bread, all while hungry birds are pecking at me. Or the other option, I go inside where birds already live and have taken over. I'm no longer the master of my own domain. The house is theirs now. My wife is theirs now. My children are theirs now. The birds are in control.
So which one is it? And sure, there are some flakey breads, but it's never been such a problem that I thought, "wow, we're really wasting so much of these bread crumbs. This could feed a lot of birds. Maybe a whole one and a half birds per week.
