According to Mercy for Animals, male chicks are of no use to the industry because they can't lay eggs and don't grow large or quickly enough to be raised profitably for meat. That results in the killing of 200 million male chicks a year.
Now, that's pragmatism. Notice, it's not that they are of no use, it's just that they are of no use quickly enough. I guess another month or two of feed is simply out of the question.
So, what is the purpose of a chick? Is it only to meet our needs. Is there not something of intrinsic value in this life? If it's value does not supercede a human's life, and as a Christian I don't believe it does, for it is not made in the image of God, mustn't it have value beyond it's utility to us, because we are not it's creator? In Genesis, humans are given the mandate to be stewards of creation. Here's another case where we are falling short.
If this disturbs you at all, I suggest getting to know a local farmer and start buying eggs from him, or from your local coop. (No pun intended)
