Help do I have an angry chicken??

We have just bought six point to lay pullets for our new allotment which we have been the proud tennants of for 4 whole weeks.  We have never had a garden before or chickens.  One of our lovely new birds (Tullulah) has just followed me round the allotment for 2hrs constantly pecking at my wellies, she then pecked at my arm when I sat down and then while I was trying to get her back into her run jumped up and pecked my finger.  I assumed we are going to get the odd peck here and there but as none of the other girls bothered me just wondered if she feels threatened by me or is it just the case that she tasted something nice on my wellies?  I feel completely rejeted by little Tullulah  :cry:

She's probably top chook and wants to be the first to get the treats  

I know I am sad but I think thats lovely, I wish more of my girls would do that, I would feel very honored :oops:  :roll:
