Lap Chicken - Chickens' First Day Out

I have one chick that is so friendly. It will come right over and almost arch it's back to "help" you pick it up to hold it.

And, today I let them out for the first time in the pen I made. They all explored for a bit. Then, that same chick came over and hopped up on my arm. I transferred it to my lap, and it just sat there and hung out with me while all the others were messing around. LOL!
