She is what I have termed an "emotional vegetarian". Some are vegetarian because they think it is more healthy. She is because she won't eat anything that an animal had to die to provide. Not even cheese made with rennet. She would like everyone to do the same but knows that won't be happening here. She wouldn't eat a fertilized egg because it COULD become a live animal if given the chance.
I do, even DD1 does. She chooses to ignore what happens to most of the male chicks. I don't know how nasty the gender selection processes is, seems pretty fast and is non invasive.
Why not raise my own chickens? Because roughly half of the chicks would be roosters. And the shipping is, well, necessary. There are no hatcheries within driving distance, not within many hundreds of miles. I figure they are like locally raised meat animals that have many good days and a quick bad one day. The chicks have a couple of bad days (travel in the mail) followed by as many good days as they stay alive in my barn and the 1 acre fenced pasture which they have access to all day every day. The last of my original 12 died this past March, she would have been 10 years old in June. My oldest 4 are now 7.5 years old. I'm sure they have forgotten their 2 bad days.
