Hello
Only recently I've learned that by placing a fence/lightning rod on a grass starter the animals won't eat that grass and it'll be able to spread every day.
So how small can I make the fenced area so that all 12 animals can eat grass every day? Let's assume that the 1 fence post+grass starter has spread area of 1 quality sprinkler (3x3 tiles). How many of these would it take to keep them fed? (and let's ignore buying hay from Marnie for the sake of argument)
EDIT: The sprinklers are there only to show the area the grass will spread from the placed object.
So:
green = grass spread area
sprinkler = replace with oobject like fence or lightning rod.
Too many people get confused by this in this post XD
