Not necessarily true. When I moved to our current house 25 years ago I raised chickens, rare breeds. We ate and sold the eggs, and excess roosters I took to the livestock auction and made some nice money. I bought my chicks every spring from Murray McMurray. We still have three or four neighbors who raise birds. No illegals here... I love the sound of a rooster crowing in the morning.
I agree with TonyStark and believe your experience to be the exception rather than the rule. What next? Goats tied up to front stoops and pigs feeding in fenced yards?
Wake up America.
