I recently got 2 females & 1 male Muscovy. They laid right away, so I had 2 clutches. Because of space issues, I let all of them go to new homes except a few. I now have five of the 6 week old girls & 1 Mom & Dad who are 1 1/2 yrs old. The girls stay penned up most of the time. Mom & Dad are free range. I do not want any more babies. I tried to catch Dad but have not been successful. Every afternoon, I let the babies out to forage some. I know Dad has nothing but SEX on the brain but I want to know exactly WHY he chases the babies? I don't think it is to mate because he did it when I had boys too. He is really aggressive towards them! He huffs & does the wing spread & the whole bit! He bites them & chases them either into the water (I live on a canal) or back into their pen. Is he trying to keep them away from the mother? Is it territorial? Is it sexual? I have run interference & chase him away but he is very determined & often will come back from behind a bush or tree in another part of the yard. He sneaks up & starts again. Is there anything I can do to stop this without re-homing him or does he need to go? HELP PLEASE!
