That might be the case some places, but not always. There are a lot of humane farmers in the world. Our eggs come from our own yard, chickens run freely without a fence. If babies hatch they grow up (both genders). You can choose not to use eggs, but not all egg users are bad, and not all egg farmers are bad. Blackheads? I cannot find any good use for them. I love the simplicity of this tutorial and the low-cost, as well as the use of things that are easily found in most homes.
