Yawning?

[Firearia]

I have one chick that is 2 weeks old. However she keeps on yawning and stretching her neck when she does so. The little girl does it quite often too, I'm really confused. She looks very healthy and is the only one 'yawning'. Is she just exausted, am I doing something wrong or is it a sickness?

Is she gaping as she is hot?

Don't know about yawning, though,

I don't think so as the others are under the light a tiny bit more and not doing the same.
