When your great grandmaw needed something she didn't run to wallyworld she made it her self .They raised a garden ,fields of grain,harvested the wild world around them. That we have destroyed it didn't matter what, they had they used every last piece of it. They didn't throw any thing away.they needed a cow,chickens ,pigs,goats,horses,all had its place, to feed and be fed.The money they made through the year on selling the surplus went for seed to plant, so they could make it the next year.They if they had a broodie hen whitch they strived to help. They took very good care to see that she succeeded. There lives revolved around trying to suvive and prosper. as would yours if things go bad. Some of us won't make it some of them didn't . The world is always in a state of change not always for the better.Being prepaired is not un realistic . Having chickens and the knowledge of how to takecare of them is one step closer but far from being able to or having the knowledge to survive , In what our future has in store for us.Sorry for the long rambling , I would think that you would start building your flock to suit your new use for them no matter what kind they were.
