Well, my drake died today...I can't be sure, but I don't think he was eating very much...He had been acting ok for the most part though, walking around and swimming in the pool. I had cleaned his back several times too...I don't know. I guess I don't have to worry about him being mean anymore, but it's still really frustrating.
On the upside, my IR female is looking really good. Her back looks like it is healing nicely, and she's still eating and quacking a lot and acting very energetic.
even though he was causing problems it still hurts when we lose them.
