I'm not new to birds. Just to ducks and geese. I know that my dogs must be kept separate. But, after 2 nights of the waterfowl going in a secure pen, after being told by the person who gave them to me, how easy to handle they are, they became adamant about not going in anything. And, my dogs need to go outside, occasionally. They're not cats, they aren't litter box trained. They have their needs too. The duck and goose got pretty stubborn, and decided to stay out. After my disabled self was done chasing them for 2 hours, I figured they'd have to deal with their decision.
I didn't want an issue, but, the dogs had to go out. So I limited their time. But, in so doing, they needed to go out more frequently, in the middle of the night, while I was trying to sleep. I got the duck and gander caught that next morning (the morning I posted this thread) and placed into a very large pen 50'x150'', that keeps the dogs away from them. It wasn't my choice, to leave the waterfowl out. They simply refused to go in. I understand. I was told they preferred to roam, so I tried to go with the instructions I was given.
But, sometimes, when an animal refuses to do what they normally do, they just have to deal with it, and we all hope for the best. Sometimes the chickens do that, sometimes the turkeys and guineas do, too.
And, no, I see no curled tail feather on the duck.
could you not use a leash?
