I can't load pix from my phone, but I can give you basics of how mine is made.
6-8 ft long, 2-3 ft wide (depends on how long your arms are)
Legs 1-2 feet underneath
Baby area about 2-2 1/2 feet high (depends on how fast your ducklings grow, you want room to hang heatlamps without hitting their heads)
Floor of entire brooder is 1/4 inch rabbit wire. Walls of about 2/3 of brooder are also wire except where access doors are. Walls & access door of other 1/3 of brooder are wood & heatlamps hang in this section. Leave an opening just big enough for a duck ready for your growout pen to get through between the 2 sides.
Put roof over top.
You can put small pans of water in the open section or make a frame in the floor of the open section to sit the pans down in.
Everything drops through to the ground to be hosed or shoveled away.
