that reminds me of a something that happened to me. In November 2012 I wrote a book about keeping chickens and sold it and as a result b had lots of people calling asking for advice on hens? one woman had intended to get broilers for meatand rang me to ask how to fatten them up. I explained the feeding regime and the general care of the birds to her. I then asked her how she planned on culling the birds and did she know how to gut and pluck them. She was horrified that I would even suggest killing them and was asking why on earth would she kill them if she only wanted them for meat. It turned out she thought chickens produced meat like they lay eggs and that they would continue to give meat all the time. That was a real shocker for me as to how someone could even think up something like that.
As for veganism, I know lots of vegans who live the way they do because they know how commercial food production works. They know how battery hens are treated, that all male layer chicks are killed at day old and that most of the time male dairy calves are shot because there is no use for them and not enough demand for veil.
