So as my ducks are getting bigger, now at 7 weeks old, I am noticing that one of them is constantly picking on one and being bossy towards her. I am almost positive that I have 2 drakes and one hen. Poor hen can't even swim in the pool without being bullied. She just bobs her head in the water from the outside of the pool. So I am wondering if this is normal or do I need to get rid of the one drake or is it ok to have 2 drakes and one hen.
