One of the older ones, which is about 3 times her height already, likes to peck her and occasionally go after her for a few seconds...I would like to think it's normal as they establish the pecking order, are we over reacting to the pecks?...We've taken her out of there for now...She does eat and drink with no problem, just every now and then they peck at her and just because of their size, we think they're hurting her...
