we have two rouens we got back on April 11 that we're positive are hens (both have made loud quacks and quack or honk when they get chatty and neither are getting any hint of starting to get drake coloring) and we're planning on getting a drake soon since we were hoping they'd be a male and a female. we just got an offer from someone who has some extra young cayuga/khaki campbell cross drakes (only slightly older than my two ducks) they need to get rid of so we're probably getting the drake soon so I'd like a few tips on introducing him to the girls. I have done some googling on this, but it never hurts to ask for more input on things like this if you don't have any experience of your own with it. is there any issues to especially keep an eye out for, and if so how do I deal with them?
