If it makes better or cheaper food hang them by their toes and shake them 24/7!!!
They are nothing but a food source, if you can’t eat them or wear them exterminate them!
To each his own.
The fact is that my birds (and their good health) are far, far more than a food source and integral to almost everything else I do on my homestead. Of course, if you think food comes in a plastic package, by all means eat whatever the corporations chooses to feed you.
Bon appetite!
How about if your food eats them but you don’t?
