I love your set up, what a nice looking place. I feel your pain when it comes to ducks and mud, they just love it, we let ours roam around and it took care of any mud problem, they seems to be more happy with nice bucket of water and a lot of green grass to roam around, mind you, we have small yard, just a little pizza cut city lot with huge house on it, so there is not a lot of room to be free, but never the less, they do enjoy it much better then enclosure, and it is much cleaner, and the grass is greener, we have not used any kind of fertilizer for years. Summer time we have them in the enclosure but fall and winter they are allowed to be free. Also we took care of duckling problem, I love little ones to run around the yard, but then they grow up to be a messy little creatures that eat and poop, so we send our drakes to the freezing camp.Would it be possible for you to share a couple photos of your pens? I'd also love some input in regards to what I need to do to make it work for chickens.
Obviously more perches and nest boxes. I'll take out the pond and dog house (anyone want a nice dog house that needs a new roof? do I keep it for silkies to cuddle in?) I'd assume roofing the run in that clear plastic would probably be useful. Should I be building an actual coop or just the particular things they'd need? I assume chickens would probably like some protection from the elements.
