They were looking for a ramp to get in. Maybe they will figure out how to get in from the dock. That is cute. I had some baby ducks and they loved to get in my bath tub. They just swam and thought they were big ducks. They made a huge mess, but nothing a little bleach wouldn't take care of. So cute.
I love their chicken friend walking around with them. I have one hen that hangs out with the ducks instead of the other chickens.
Did they find the ramp? I once just moved the ramp to my duck pool and it took them 3 days to "find it".
