The pen has a nice layer of straw in the ground that’s nice and soft. I have a drake that has very weak legs and he likes the straw so about 3/5 of the pen has a nice thick layer of straw
the rest is the ground but the dirt is soft in that part of the yard.
We tried keeping her inside for a bit but she just kept honking and was so sad. She wants to be with the other ducks in the worst way.
she keeps her wrappings on at night for the most part so I think the other ducks are helping her take them off during the day
Sorry I forgot to respond to your answer! It sounds like you have excellent soft surfaces for her to walk on!
