Good morning! We have 15 Muscovy ducklings that are 4 weeks old and I'm looking for some advice on which are male and female please. Also, at what age do the males lose their voices? Here are some of the clearer pictures I was able to get this morning along with a group shot of all my ducklings and adults (minus one hen), plus 2 baby turkeys
Thank you in advance for any help!
