Should my about 2 week old chicks be tilted when laying down?

[CoolChickenPerson]

My eldest chicken which is about 2-3 weeks old has recently begun to sleep more tilted on its side, not fully, but noticably the chick hasn't shown any sign in injury it tends to even fly from time to time. Is this normal for a chicken?

A picture would help, but it sounds like normal behavior.
