Hate to dig up an old thread but feel that it is needed since it has recently come to light again over filial designations.
Since this thread was originally posted on Fauna, I took the time to contact everyone working with the Dunners and composed an in depth article for our website. This involved making contact directly with the breeders and gathering facts first hand. When this article was complete, it was posted on Fauna for everyone to see.
I made the mistake of not digging up this old thread after the article was completed and correcting any errors on my behalf.
The article was public and being that filial designation was specifically covered in the article, I thought that it would speak for itself and supersede info posted on an old thread.
The following is the article for anyone whom didn't see it.
