Farming in LV

I am have currently survived for nearly 2 months in Rosewood and it is my longest run, but since i now have to take a roadtrip to get resources from either Fallas or Muldraugh or Echo Or Marchridge(there is never anything good in marchridge) So i have been thinking is there any feasible way to get animals and an animal trailer in like Valley station or LV and WP because i plan to live in those 3 fenced off houses in LV, and i would also like to ask what zombie population should i play on so the zed pop in LV is low even after peak day, and no i dont plan on moving to LV i will do that in my mext run
