I don't live in suburbia. I didn't ever really talk to her, but I know she moved because she got sick of my rooster.
I don't think your adjacent neighborhoods have yet learned that they'll lose money raising chickens.
As they say, if you want to become a millionaire raising chickens, start off as a billionaire.
As it is, statistics show the backyard poultry fad is rapidly fading. More and more people are getting out of chickens as, again, they are learning that they are losing a lot of money. Coupled with lack of veterinary care and a short lifespan/lay period, chickens are not suited to be the next suburban household pet.
