Do Hamsters ever not want to be held?

[Tinky]

Hi all, Hope your all good.
Im just wondering about Pebbles,

She is very friendly (and a bit mad lol)
She responds to my voice, will get in and out of her own ball with no trouble,
She Willingly walks onto my hand if I have food on it, she will climb over my hand when I'm filling her food bowl, but wont let me pick her up.
If I try to stroke her, or pick her up,at all she jumps and skitters away, She seems very friendly just doesnt like to be touched, Only if she is doing the touching lol.

Is this normal? Is it just her being a baby? (11 weeks), Or a settling in thing (we've had her 5 weeks), Or has anyone else had a hamster that doesnt like being held.

Thanks in advance for any replies xx
