I adopted two khaki Campbell’s as babies and have had them since. They are free range and always go to their coop at night without fail. They have been free range for over a month now. They are around 3 months old. This morning as per usual we let them both out and they were perfectly fine then this afternoon (we were inside and outside all day so if a predator had taken it there’s a good 75% chance we would of seen it.) I heard my what I believe is a drake crying loudly and the other was gone. They have never ever left the yard or each other before and now he’s been crying out back for hours and still no sign of her. It’s going down to 18 degrees here tonight and he is alone now. Any help with where she would go? I’m not positive it was a girl. What should I do with him? I’ve never had ducks before. I posted a picture of both of them and one of the one I have left.
