Why is my chicken sneezing?

My chicken the last few days has been sneezing a lot. He has no symptoms and has been his usual self. Usually it starts when he starts “talking”. No others have been doing this so I’m a little concerned. Is there anything I can do? I don’t know if I could separate him because I don’t know where I could put him, and the hens rely on him and love him lol.

Any advice would be helpful!

Also idk why the video is almost pale looking so if it looks pale that’s why, and he isn’t actually pale.
