I've been really sad about this, and therefore haven't been online to ask until now. Last week, my mandarin hatchling showed signs of neurological problems and died shortly thereafter. I know there's nothing I could have done, he was acting perfectly normal just before and within 2 hours digressed and passed away. I asked my friend who bred the ducklings how hers were doing and she said that she found them all dead without signs of external force (i.e. predation) around the same time. So, what happened? I know she got her four adults from McMurray hatchery, could this be a result of inbreeding or something? I was pretty devastated and am now back to square one looking for a suitable friend for my current duck. Thanks for the help!
