Which world does he live in?

Frauenfelder's book Made by Hand obviously focuses on Do-it-Yourself-activities and still I am buffled how ignorant towards other benefits of his enterprises he (and his family) is. The first chapter was about replacing his lawn with a vegetable garden. The second one was about mending his espresso machine to make better espresso, something I can't relate too because I am no coffee-addict nor would I bother to cause myself high blood pressure by drinking espresso. The third chapter is about his chicken coop. Apparently he wanted to chickens for the eggs, although building the coop was the major DIY-job, but once the hens start laying eggs his family is all put off. On page 109 he admits that they buy packaged food, including eggs in a box from the refrigeratored shelves in the supermarket, and it obviously did not occur to them that this food comes from living creatures. The fact that the eggs slip out the hen's bottom upsets them. So it takes the family a while to actually overcome their absurdism and consume the eggs. Shockingly, when his kids bring friends over they all react the same, can't believe the eggs are edible and keep them as toys instead.  

I don't think I need to point out in detail my reaction to his revelations. I have a lot of trouble to believe anybody, ANYBODY, could be so disconnected from their food sources, have such a city-dweller attitude of "food comes from the supermarket", that they have trouble eating certain products like eggs once they realise it comes from an animal like a hen. What do biology classes teach nowadays? I bet Frauenfelder and his family could not drink milk from a cow milked in front of their eyes. I wonder if his wife breastfed their two daugthers. At the beginning of the book he mentioned that they took a breast pump when they moved with their newborn to the Cook Islands. 


Also, he does not mention anywhere that his home-produced food should be healthier than supermarket stuff. He notices the eggs look and taste different but does not seem to come to the conclusion that this is because the hens aren't battery-kept and fed on grains.  Unfortunately, his vegetables aren't necessarily poison-free. Until he got the chicks he had pest control come in every month to treat his garden against insects, spiders and beetles and such. He stopped doing this in order to not poison the hens. It did not occur to him that the treatment might harm him directly or through being absorbed by his produce? For him it's all about the experience of creating something with his own hands. He does not even mind to buy whatever it takes from the hardware store to complete a project. More accidently, he realises there are cheaper ways and he for example can use scraps from his junk pile that he tends to have in a corner of his garden.
  
I appreciate that he gardens, keep hens (and later in the book probably bees too) and gets his hands dirty. I would love his efforts even more if he considered his impact on the environment too though.
