Yes, its normal, he's just playing around. My girl does that when she's playing in a bowl of greens.
However, you should not let them chew on your cords. They can and will chew through the thin plastic casing on the wires, and they could get seriously injured if they do. Be sure that if they are out while you are using your laptop, the cords are covered or are where they can't reach.
and Princess Mallorn!
Thank you to Deb for her wonderful Faery magic
Thanks for the confirmations that he is just having fun! I just wanted to make sure it wasn't because of anything clinical. It was new behaviour, better to check of course!
@StarlingWings I know they are not supposed to chew on the cables, and I don't let them, it just happened in the moment of the video. On the right is actually a wooden playground they usually play on. There is bark from it all over the table in the video, they are messy little chickens.
@Rainyday Thank you! I'm in love with their colour too. I have no knowledge of mutations though, sorry. I do have some better pictures, maybe that could help:
Lovely nibbles from Kimmy and Jimmy!
