This morning my mother-in-law brought us a Black Swedish drake. She has a rather large pond and we figured that someone just dumped him on the pond about a month ago. He had shown signs of being friendly, so we tried to catch him a couple of weeks ago. But he was enjoying his freedom to much and wasn't going to let that happen. Well this morning my mother-in-law was down by the pond and her small dogs found him and started to chase him. He pretty much ran straight in to her arms looking for safety. So she brought him to us. The poor guy is very under weight and was very hungry. I gave him some food and he started to eat it so fast he nearly choked on it. Right now he is only getting a small handful every couple hours or so. So my question is what is the best way to feed him and to get weight put back on him? We have some mallards and call ducks, but I have never had to rehabilitate a duck before. Also is there any way to age him? Oh and he is quarantined away from our other ducks. Thanks for any advice.
