We just got finished building another coop/brooder for 16 ducks(they are day olds now). It's dimensions are 16' long x 3' high x 4' wide, there is also a 4'x4' house for them on it, so their run is 12 ft. long. It took about 3 or 4 days to complete, it's new residents were brought in it tonight, and they love it. It's a little big for them but I think they'll grow into it. Here are some pictures...
