I am just outside of Crown Point, IN - my neighborhood has gradually been changing over from small farms to subdivisions.
Hopefully the devlopment will stop where it is now - just North of me.
When I moved in here 5 years ago, there was one flagged lot - there are now 4 new subdivisions
Zoning laws changed since I moved here so nothing less than 10ac can be sectioned off into multiple homes.
South of the latest area to get built up is mostly small acreages and it looks like people are holding onto them so far.
Zoning laws have also changed re: livestock. It used to be you had to have 3.5ac for the first large animal and an additional acre for each one added. So my 5ac was just legal for my 2 horses.
Now you need 5ac for the first large animal.
Sorry, but I don't know the limitation on poultry. My neighbor immediately to the North of me has about 15-20 hens and 2 roosters. I have 5 pullets.
Several of the others have horses, but I haven't seen other poultry. There is one small hobby beef farmer to the South.
