Hi, I just got my fuzzy butts (6 BOs and 6 Speckled Sussex) earlier today and I've been watching them. One of them (a SS) keeps pecking at everyone's egg tooth (the little white bit on the end of their beaks, especially pronounced on the Sussex as they have dark ends on their beaks and then the white tip). Is this normal behavior, is she just trying to establish her position as top fuzzy butt, or should I start being concerned that this fuzzy butt is aggressive? She seems to be the only one doing it. They are 2 days old, hatched on Wed I believe.
