I do not understand the mathematics behind the dilemma. I'm assuming only the firts chicks cost money, because down the line they will breed.
But feeding them, housing them - vitamins and doctoring costs a lot of money.
So anyone with couple or more chickens - how much does it cost to have them on the table? And realistically how many eggs do you get?
Well, the offal is not considered awful by probably more "rural" people, as well as soul food. People who traditionally have been more poor and so make use of more of their resources. heh.
I don't particularly like chewy gizzards, but I ate them growing up - mom would fry a chicken and out of love fry up the heart, liver, gizzard, and neck and that would be a snack for me. And I love fried chicken livers... it pains me that I can't find a good local source (because I try not to fry - it stinks up the apartment for days - and I've found that fried chicken and livers and certain other fries foods are often better in commercial operations/kitchens). heh.
Dammit, now I'm craving fried livers! lol
But......... while you can find chicken feet for sure, and chicken necks, I'm not so sure about chicken heads. I'll grant you that that one goes to my "squick" factor. heh.
