I haven't had ducks as an adult, so I'm kind of flying blind here. Please let me know where I need to improve upon my plan, what I should scrap, and what is on point! *We're planning on getting 3 females to start off with, and next year may get a drake to hatch some ducklings out for meat. *12x12' enclosure (144sq ft) *Enclosure will be situated on a slope which should help with drainage *Enclosure will be 6' tall, with half of it covered in clear corrugated plastic, the other half covered in wire mesh - covered portion is the area that gets more shade, open portion is the area that gets more sun *I intend to sink a pool of some sort into the hill and surround the whole area with smooth rocks/pea gravel, and run a drain out the bottom and out the pen to fill watering cans for my veggie garden *House will be similar to, or a doghouse that has a hinged lid for easy cleanup - interior will be painted and the bottom lined with peel & stick vinyl tiles *Waterer will be a 5 gallon bucket with holes cut in the side for heads to be inserted, Feeder will be a PVC hopper style. I'll make something similar but smaller for oyster shell *Soil in the run is a fine sand, I figure I'll leave it as is until I determine how messy it gets. If it gets bad, I'll probably do gravel on the side that'll be getting rained on, and straw on the side that stays relatively dry (makes great compost or garden mulch) *Primary wire will be 2x4 welded mesh. We do not have predators to speak of, and we have (primarily indoor) dogs so things tend to steer clear of our yard. I will see how the 2x4 works, and if it's not sufficient for the bottom portions, I will add something like 1x1" to the bottom 2' of the walls. The 2x4 welded mesh will be buried about 1' into the soil to help prevent anything from getting in there. *We're in the Seattle area, so are used to moisture and drainage. *The pen will be their primary home. We will free range them when we're out in the yard, but we both work full time jobs, so this will be the exception, not the rule. Other things I'm considering: *Eventually trying to figure out some sort of biological filtration system for the pond. This is not high on my list at this point, but it'd be nice eventually when I run out of projects *Sprouted fodder feeding *Some sort of water catchment from the roofed area to fill the pond Questions that I have: *How much oyster shell do females generally consume? *Am I going to need nesting boxes or just see where the ladies start laying and go from there? *It doesn't ever get into single digits here, am I likely to need a light/heater of any kind this coming winter? *Are tumbled concrete pavers (the decorative ones with rounded edges that people use for patios) likely to cause bumblefoot? Should I stick with river rock/pea gravel? *What am I missing?
