This winter I have kept my ducks in the greenhouse which is 8 by 15 feet, it is divided in 2 by straw bales, One half has my 9 egg ducks and the other has 13 pekins which will be butcherd and of this month.
I have almost finished the duck house for the egg layers. The overall dimensions are 4 by 6 feet. I used 2 by 6 for the floor joists and 2x4's for the walls. The roof is 6x8 feet to provide overhang. I took 2x4s and ripped them down the middle for the roof joists. The skin is all half inch plywood I bought surplus. Lastly, the wall panels were bolted down with 1/4x4 inch lag bols and screws so if i want to mmove it or sell it, i can break it down easily and quickly. All in all I spent very little as it was all surplus aquired off of craigslist.
The floor space is ample for the 9 ducks and soon 10. I have decided to seperate the Rouens, and the White Golden egg layers, and take the best male Pekin and add him to the White goldens to cross for abundant fertile meat duck eggs. there will be a simple divider down the middle. I use wood grape boxes for nesting and they like it and it really keeps the eggs a lot cleaner.
Each side will have their own run that is 4 x 12 feet. Each will have their own kiddy pool for bathing. I have some preliminary pics but do not know how to load. Email of pm me and i will send you some.
I use wood chips from tree services for the outside surfaces so there is no mud, and the inside has hay which i sweep up at the local feed store. i like the timothey hay since it smells sweet, the ducks like to forage through it and it does not stain the feathers. Also it gets very hot in the compost pile, but most of all it is FREE. This spring I will role up the well-pooped on hay underneath the planting beds and add 10 inches of topsoil, so the bottom and roots will be nice and heated this March.
