I got my ducklings 3 weeks ago and they are almost 4 weeks. I’m just wondering if young ducklings can flirt with each other. I sometimes catch them flirting. For example I take them on a swim and they swim under water with their necked stretched. According to this website I read that’s flirting. They are also very cuddly with each other. Do you think they are flirting? If they are flirting does that mean one is a male and one is a female?
