Have any of you ever experienced a pullet who has undergone a complete personality change as she approached point of lay? My Welsummer was the sweetest bird in the flock until last week. She would come over to greet me and enjoyed being petted and even carried around. Now, however, she puffs up her chest and challenges me every time she sees me. If I ignore her, she'll escalate to pecking at my leg - HARD! - or flying up and trying to flog my legs (it's a good thing she doesn't have spurs!). Sometimes, she'll be her normal sweet self, but most of the time she acts like she's been possessed by a demon. She's too small to do any real damage, but I'd still prefer not to have to deal with that kind of behavior on a daily basis. I'm hoping she's just reacting badly to her changing hormones and will settle back down soon. She's 21 weeks old now. She WAS my favorite bird in the flock, but my affection for her is rapidly wearing thin. Otherwise, she may find her way to a crockpot or on Craigslist soon. I'm finally making progress on getting her to roost at night instead of sleeping in the nest boxes and now this... She's perfectly healthy and is definitely a pullet. The chickens have more than 8 square feet per head in the coop and about 20 square feet per head in the run, plus they get to free range for a few hours most evenings, and she's not acting like this to the other birds, just to me. So, any ideas? Past experiences with a similar behavior change? Moral support?
