Hello, Maralynn28,
I sometimes think of ducks as kind of Quakerly. They want things simple, and basic, and they appreciate the simple things in life.
The metaphor only goes so far, but really, they need few things, but some are a challenge to provide.
They need reasonably clean water daily for drinking, reasonably clean water daily for washing, nourishing food, safe shelter, the fellowship of others in their community (a flock).
Some like nest boxes, many don't care. They make water dirty very quickly. They like to "drill" in the soil.
Cozy - well ventilated but not breezy, plenty of clean, relatively dry bedding. Decent lighting (I am using gray sun-tuff on outer edges of roof, clear sun-tuff down the middle). Half inch hardware cloth over any openings, no opening more than half inch wide (weasels can get in through a 1 inch diameter opening, I am told, and raccoon paws can reach in.
I don't leave water in the brooder overnight with my seven-week-olds, and don't plan to have any food or water in their shelter. It will be in the night pen securely attached to their shelter. Then I have the option of letting them have access to it overnight or not. I would like to, but I am concerned about predators in spite of my Little Fort Knox.
