Honestly it depends on the gameplay loop designed for a title if that would work.
Ideally this type of situation should occur as an upgrade to the farm. In games where this is being done ideally they are running a number of actions a day solution or an energy solution where new jobs are being introduced as you make old ones more efficient. If I had to make a choice I would use the time of day (separating day into multiple parts [early morning, morning, noon, afternoon, evening, night at most]) and having repairing/building a ranch/farm be part of the campaign/story.
This would allow for a sense of progression (other than unlocking new monster types) that would be massive for the player's gameplay loop. This is more of a resource management game focus though than a storyline point. It also means that improving the efficency of the ranch/farm is an important gameplay element (which it should have been in multiple games). If a major plot element is the farm being significantly in debt or needing to improve profits to survive this type of gameplay progression should be in the game.
