My female pekin laid a nest and did not sit on her eggs so i brought them and incubated them. 2 of the ducklings hatched. I took them outside and daddy pekin keeps bullying them? They are now 2 weeks old and i keep trying to introduce them but he does not seem to be adjusting. Is there anything i can do to keep my male aka daddy from being mean to the ducklings? Thanks for any advice!!
