So it's the first day my duckling are going swimming and i have never owned a duck before but I have two. ones a kakhi Campbell and the other is a magpie. Is there anything I need to know about these breeds when in the water or what temperature or how much water to fill up in a tub ( just a regular bathtub inside the house, it was cold out today and it's their first day I wanted to be good experience for them) and how long to be in the water? I will put pics up here too. Thanks!
