So I live in eastern Pennsylvania. I have one Pekin duck probably around 10 months old and I have two Rouens who are around 1 month to 2 months old. I just want to know what is normal behavior for an adult duck to act towards the babies. So far I've noticed that my Pekin sorta circles them and sometimes even chases them down and tries to lay on top of them. I stop her right away because I don't know if she's going to hurt them, so I just wanted to know if this is normal or is she just being a bully. Any input will be greatly appreciated. Thank you!
