When oh when are ducklings old enough to be in a closed duck house? They are currently being housed in a large baby pool with cardboard around it, in my garage. Today, I go out, and they have eaten a hole in the cardboard surrounding their pool and the crested (of course) escaped into the garage. Not sure if she is the smartest duck, or the dumbest duck, but anyway, they are four weeks old now. Is it too soon for them to be in the duck house? It is completely enclosed with solid floor. Predator proof. Refurbished especially for them, no other birds. It is getting into the 80s during the day and the 60s at night. Any suggestions? Just say yes! Please!!!! Haha!!!
