Sorry for not responding sooner, work has been busy! All our birds are in a coop with a 18x30 run, and they free range AT LEAST 5 hours a day, and all day on the weekends. Our birds are all 18-21 weeks, I believe this drake is 21 weeks. I’m kind of confused, because up until yesterday, he was definitely the bottom of the pecking order of the 13 birds. We have never seen him show any signs of dominance/aggression/interest in anything.
We do have a dog kennel that I considered putting the ducks in, but they would be in there with the dogs during the day. The dogs haven’t shown any signs of aggression toward the birds (they actually play together) but I wouldn’t trust them being locked up together. I appreciate all the suggestions...I don’t want to get rid of them, but that may be our best option at the moment.
