I do have them on medicated starter at the moment (I know! Please don't turn on me!!) I highly doubt that is the cause however as she was like this when I picked her up and was on a very pricey organic starter and had vitamins in the water. The breeder is well known around here and has amazing birds. She also is not exhibiting any of the other symptoms. I can grab some liver on the way home anyways. It never goes to waste between the dogs, cats and chickens Unfortunately the link you provided did not work for me.
