Hello! I'm new here and live this forum . I have the pleasure of having the friendship of a mallard drake aka ducko/duckin/fat butt, that is about to turn 1 year. He is healthy and happy but what I've notuced in the past month is that he does not wash his face or back when he's in the bath anymore :/. His feather on his head are crusty and around his eyes are balding. His eyes look healthy though. He has and us 100% inside my home since a fuzz ball so I do not think it would be pests. He lives to just soak in bath but won't dip head and splash onto backside like he used to. Has anyone experienced this ? This am I tried running shower off to side to see if he'd like that to no avail.
