Breathing Sound

[Efe]

Hello, my chick is about 2.5 months old and sometimes I hear a breathing sound from it. I used to notice this while it was eating, preening, or doing similar things. I thought it was normal since it seemed like it was just pulling air in. But today, I also heard this sound while it was just sitting. Later, while it was preening again, I heard the sound a lot, even from a distance. Is this normal?

Sometimes there can be sounds coming from its crop, like stomach rumbling. It also happens when it drinks water. It doesn’t happen all the time.
