There are ideas to add a gate for the fence, thus creating a pen, and add chickens, and nests for them it will be more interesting
In this category I will add:
In the fences category: Something that look like the railings of the stairs.
Those will be useful as decoration at porch, balconies and stairwells.
And I would like that wild animal did stay out of buildings.
It looks a bit weird with wild cows indoors.
Wild cows opening and closing doors are a bit too unrealistic to be believable.
I agree with this,you need to add paddocks to the game, or a gate for casting,
