I was going to go with being pecked on as well but if she's doing the damage I'd have to guess something is bothering her.
Did all the BA's come from the same place? The 2 I got from Ideal in 2012 had slate legs, pink feet, per the SOP. The 2 I got from Meyer in 2015 have black legs and yellow foot bottoms. That fits the BJG spec. While they claim they aren't BJGs (and they aren't based on size alone) I'm betting someone decided they needed some size in the BA line and inserted some BJGs in the mix somewhere along the line.
