I have 3 girls around 27 weeks. they have been brought up together and when I got rid of the roos around 15 wks, I noticed a little bit of squabbling, I'm assuming they were rearranging "pecking order" all was fine. They all 3 just started laying for about a week now. The one in the middle of the "pecking order" Is all of the sudden picking on the other 2 like when I give them treats or just observing them running around the yard. It's almost as if shes trying to "Mount" them and pecking at their necks!! Do I do anything or just leave them be? Does "pecking order" change when they begin laying? or just raging hormones? I dunno, Please any advice would be great.
