Now that begins to make sense! - Some time ago if found my Buff Orpington drake Erpelchen beaten up pretty bad, ruffled up plumage, missing feathers, swollen eyes, the whole packageā¦

I had no clue what happened, but after looking into the table in your article, there are only two ways how this duckling could have been created: Erpelchen must have mated with one of the Black Swedish ducks - and got caught in the act by Ralphie Dux, the Black Swedish drake... ā
Ralphie is twice the size of Erpelchen.
