This evening, one of my 9 wk old little chicks jumped on the back of an adult layer hen, pulling her hackle feathers, as if to mount her, dominate? Something like that. The hen squaked as if she was wondering wtheck are you doing?! They have all been together for many wks. There is a rooster in with them all. Wishing I would've had my phone to snap a pic or video it, but didn't. What do y'all think?
