Curious about a behavior I am seeing

[HennHouse]

My girls are 2 weeks old today and I have been noticing when I take them out to stretch their legs and forage in the yard they will run up to one another and bump chests...Is this some kind of pecking order behavior I am seeing? So very cute to watch them interact with each other

Yes it is. It's play for now, but it's practice for later when they establish who's the top dog.

Mine did that all the time! Now they poof out their neck feathers and have stare downs.
