My girls are very friendly. Or they're creepy stalkers - I'm still undecided.
They follow me around the yard, and wait for me on the top of my stairs where the back door is, trying to get my attention through the door. Only one lets me pick her up willingly, but the others put up with the occasional pat. (The rule here is, if you get too close to my feet when I'm walking then it means you want me to pat you! LOL)
They're Black Australorp hybrids (crossed with ISA Browns). They give me an egg a day most days, forage well around the yard, destroy all the groundcover under our trees, and fly up to my lap when I sit in the yard with a cuppa - just in case I have something edible for them. They also are quite laid back when my baby and toddler follow them around the yard.
We only have low fencing around the yard and they've never yet left our property (Small suburban backyard).
