Moving the Ducklings outside...

That's an excellent idea! Though, I must say that I think this style of brooder is much better suited for chickens (as that is what my brother originally designed it for) than for ducks. For ducks I would have made the walls much higher so that they don't have to duck down their heads so much when the lids are closed. Also, I think it would work much better for ducks if it were much lower to the ground. Though a raised brooder is more convenient for the humans who change the food and water and come to check on birds, without having to bend over or crouch down, but the way I am brooding my ducklings is much different than I do for chicks who pretty much stay in the brooder all the time until ready to move outside to a pen. But for my ducks, I am letting them free range the yard during the day, and it is a bit challenging and stressful to ducks having to pick them each up in order to move them in and out twice a day. I think that a box that sits on the ground and has a door that could be opened to let them out and then corral them back through again later would be tons less stress for everyone!

You have young ducks! They are no longer ducklings. If those were mine, they would sleep in the duck house and free range during the day. My Spring ducklings were almost fully feathered in early March, 2½ months old and i let them loose in the middle of a snow-shower… Had an Infrared lamp in the duck house for about a week before i noticed they were actually avoiding it. Ducklings grow so incredibly fast…
