Only in the sense "Männchen" (Männeken) of the OHG trahho
(<*drako) in forming OHG an(t)trahho > NHG Enterich.
(BTW, in Bavarian, die Ente = de Ant'n.)
Gänserich, Täuberich, Mäuserich are formed according to the
anttrahho/Enterich model.
Otherwise -rich simply means masculine. Note that even in
today's standard German male and female animals are called
Männchen & Weibchen.
Wüterich ("extremely furious; cruel") seems to follow another
pattern: OHG wuoterich.
Fähnrich existed in OHG as... faneri.
So these have in common with Friedrich, Ulrich, Dietrich,
Dittrich, Heinrich, Erich, Helfrich, Wintrich etc. the fact
that -rich is perceived as a masculine ending. (At least as
it has been in MHG and NHG.)
