Hello! Our duck house is almost complete, ready for our 6 ducks that are about 2 months old. I don't have the pen built yet, and I'm starting to wonder if I need to. We live in a neighborhood in the city with a normal sized backyard (probably 50ft x100ft) and a LOT of tree coverage. We have a dog that stays indoors while we're at work, but I'm pretty sure most critters and neighborhood cats know that he's there and stay away. There are also dogs all around us that stay out all day. My neighbor has chickens, and I don't think anything has ever gotten to them. Do I still need to build a pen for these ducks to stay in during the day before we put them outside permanently? Could we put them outside and then build the pen in the next few weeks? The usual cleaning that used to get rid of their odor doesn't really do the trick anymore. We and the ducks are both ready for them to be outside all the time. On the weekends we put them out pretty much all day and pull them back in at night, and they seem to do well. It's funny that they come next to the house when it starts getting dark like "we're ready," but scream bloody murder and try to run when we pick them up. We'll have to train them to go to THEIR house. Very excited about it. Thanks for any input.
