Using Music to raise chicken Happiness.

[Confuseddp]

How would it work? This is a good idea, but it's "just a concept" with no way to execute it.
Like do different instruments give different effects?
Does music from the DJ effect things?
What counts as "music?"

If so I do say using the vuvuzela will make them sad.

Oh that sounds good! I'd say while being played they create a slow passive increase in happiness, but different instruments like that can have the opposite effect like you said.

However, they'll slowly start to adapt to the music over time, and have the opposite effect.

I'd imagine you can switch up instruments if you want to keep them entertained.
