Sleeping in water fountain?!?!!!

[Backyardbarngirl]

So one of my new chicks about 2 weeks old is sleeping in her water fountain... Any ideas why? I am worried about her, but other than this she seems happy,healthy, and normal.

I've read about the chicks doing this--like it's normal for some birds. Also read put in large rocks to keep the little ones out. GL
