gonna have 5 ducks and 5 chickens. the chickens are gonna sleep in a seperate area with roosts while the ducks i was hoping could fit into an indigo extra large petmate dogloo with the extended entrance. it is 30" wide in the igloo part so its around 6 square feet. Is this too small for 5 ducks to sleep in? It is only for the night, i let them free roam during the day. I just thought it would be a perfect place for them because ducks naturally lay there eggs on the ground.
