How to introduce 2 females to bonded pair?

[loneralli]

I recently got 2 new female ducklings (rouen), they are 2months old. I also have a male and female (rouen), they are 2 years old. I've been trying to slowly get them use to each other. Have one in a pen and the others roam and vise versa. My issues is my male, he seems very aggressive towards them. He puts his head low and paces around the pen and tries to put his head thru the bars to nip at them. What should I do about introducing them fully?

If you have a run or enclosed area for them, just add them. The drake is, of course, going to show the ladies who the man is. With a 3:1 ratio I wouldn't worry about injury.
Good luck!

Your new Hens are too young to be introduced to your Drake...They are not mature enough for him to breed...He will injure them..Keep them in separate pens till your new Ducks are more mature ...It might take till they are 4 to 5 months old....

Thank you, we are building a separate pen now. We have discovered that Metzer Farm didn't send us 2 females. They sexed one of them wrong, one drake and one female is what we have from them. Should I email the company about it?
