Okay, relatively new to ducks, i only raised two previously. Now have 11 who are 2-1/2 weeks old. They have quickly gone from flight cage, to 40-gallon rubbermaid brooder, to shower, to a large kennel brooder (pics attached). But now this is seeming small and it looks like they would like a water source to bath in, so i gave them a pan - way too small. They seem too little to be outside, yet too big to be where they are. i'm not sure where to keep them until they are big enough to join the older one (and that pen will definitely need to be expanded). i've seen brooder pics and then adult pens on here, some of them are pretty fabulous. But how do you house them when they are teenagers? And at what age do they go outside? Here is what i'm using now. Large dog kennel put together at openings, food and water on one side, sleeping quarters on the other side. i also have a wood and wire cover for the top, and drilled a drain hole and installed tubing on wet side to drain excess water out.
