It's interesting that your chicken enjoys listening to music! While chickens may not have the same musical preferences as humans, they can still respond to different sounds based on their pitch and rhythm. If your chicken seems engaged or relaxed when listening to music, it may indicate some level of interest.
If your chicken is uninterested in classical music but enjoys Michael Jackson, it could simply be a matter of individual preference. Chickens, like people, can have unique tastes in music!
Introducing Bon Jovi or other genres of music to your chicken could be an experiment to see if she responds differently. You can observe her behavior to determine if she shows any signs of enjoyment or relaxation while listening to the new music.
Ultimately, providing gentle and soothing music in the background can create a calm and pleasant environment for your chicken. If she seems content listening to Michael Jackson, there's no harm in playing his music for her enjoyment. Just keep an eye on her reactions and adjust the music choices based on what she seems to enjoy the most!
