Thank you all for the quick responses. Now that we know what they are, their behavior makes a lot more sense. These are our first ducks, so it has been a trial-and-error process, but they seem to appreciate their accommodations.
We I’m new to duck ownership, and we rescued these two from the local animal shelter. We are estimating they are 2-3 months old. I’m thinking the male is a Muscovy, and the female is a Khaki Campbell. Can anyone verify this for me?
