Are these Quail cold?

[isegal]

5 button quail a bit over 3 weeks. Their temp is around 78 degrees. Are they cold? Also, I've noticed one lightly pecking the other. Affection, or the pecking order?

Huddling together like that means that they're either cold or scared.
Pecking could mean that they don't have enough space. It's not a sign of affection.
