4 week old spitting or very clear vomit?

[Winsor Woods]

Last night I saw, for the second time, one of my GLW's spitting up or regurgitating a very clear but viscous liquid. They appear to be healthy and all act normal. I'm not sure if it was the same chick that did this both times, but I'm wondering if it's cause for concern. After she does this, normal activity resumes with preening, scratching, eating, drinking, sleeping, etc.

I've seen this when my birds drink a lot of water quickly or they drank a lot and something squished their crop -- like a bird reaching through a cage to get something -- the contents in the crop just comes up. I don't think it means anything bad.
