So I have 2 drakes and 3 hens, all adults. But I recently got 3 ducklings. They're now about 7 weeks old, fully feathered and quite big and I've had them in a movable run that sits inside the larger run to keep them separated from the older ducks for about 2 weeks, putting them up in the pen at night where the older ducks can't reach them.
However, a few days ago I took them out of the movable run, because I want my mean rooster in there until I can re-home him. I'm tired of his aggressive attacking and stripping the back of my hens. BUT, now I have my 2 drakes going after my 3 ducklings. Mostly it's just the one, or so I thought. My Cayuga, grabbing the back of the necks of the Cayuga babies and looking like he's trying to mate them. I stopped that quickly and penned him, and opened the run for free- roaming so the other ducks can run off across the yard to play in my neighbors ditch and my ducklings can have some space, I then walked my adult Cayuga out with the other adults and released him with them so he wouldn't have reason to go after the babies again. This works fine, it seems, as long as they can free roam the whole yard. The babies have plenty of places to run off to and the adults have certain favorite areas. But today it's going to rain, I have to keep everyone in the run because not only do I have 7 week old ducklings that might not know to take shelter in the storm, I have almost 12 week old chicks who are still learning to free-roam, too. &My adult Cayuga went straight for the babies AGAIN. I put him in a dog crate for a bit, and walked away, just to hear my babies screeching and my adult crested Pekin going after them this time. Now they're both in a dog crate, but can't stay there all day.
I don't mind separating the run, but I don't know how to do it alone and any time my husband has had his weekends we've gotten rotten weather these last few weeks.
How long can I expect these males to keep going after these little ones??
