No kidding
I thought pullets were supposed to calm down once they start laying, not the opposite... Or at least that's the usual story on BYC threads. Maybe it's more individual than that. Some get rowdy, some chill, others don't show any difference in behavior. Mine weren't rambunctious at all when they first started laying, and right now out of the ones in the process of resuming, the hen that actually laid has shown no change in behavior at all, it's just the one that's about to resume that's flown off her handle. The others are acting normal, too. Joining in if she initiates some BS, but not starting trouble on their own. So I'll chalk it up to individual variation, likely related to the impending egg-laying (in other words, PMS

).
