OK, so today my Buff Orp, 18 weeks, started squatting (yay!). I noticed while she was out free ranging that she would occasionally stop what she was doing, sort of semi-squat, and her vent would get very pinkish-red and visible. She would do it for a couple of seconds, 10-15, then she would go back to normal picking/scratching/being curious. She's done this a few times today. Is she close to laying? My Australorp has been squatting for a week and hasn't had this behavior. I just want to make sure this isn't a sign of anything wrong. Otherwise she's totally great, eating, drinking, looks good.
