Fantail behavior?

[Hillybean]

Hey Everyone,
k, so I took in some Mindian fantail project birds. I believe that means they are Indian/American cross...

They are new, but when I go near them they put their tail up over their head like a shield....

Is this normal???

I had a fantail Val, that looked exactly like them, but she was bigger...She never did this, but she was calm and relaxed with me.

Anyways, its very neat...but I just have never heard about or seen this before.

BTW: Only my White two do it...the smaller one that is dark doesn't..at least not yet.
