Each day I walk them down to the pond at the back of our property, but so far they don't seem interested in getting in the water. So I fill up a large plastic container with water and let them swim and wash twice a day.
The smaller duck (the female I'm guessing) is very affectionate. If I sit on the ground, she'll eventually come over and let me pet her. She also likes to climb up in my lap. The larger one (male?) is not as affectionate, but he will climb in my lap too if he sees her do it.
I'll have to decide on names soon. I thought I'd wait until I'm sure about the genders. I'll know if one's a drake if a tail feather curls. As soon as I know for sure, it's naming time!
