We just converted our stone pool (50x30) into a fish pond. Right now our 2 Rouens mostly spend their days free ranging back and forth from their small pond which feeds the new pond. They are able to pretty much walk out of their pond at one spot but they are unable to jump over the wall which is about 10" high above the water level. The drake tries but falls back in. They have not tried to go into the new pond and I am worried that, if they do, they will not be able to jump out. The walls are about 6" above the water level. Does anyone have a similar situation? Thank you.
