It's 57 degrees F (forecast is a high of 61), and rain. The rain is chilly. My four-week-old, partially feathered Runner ducklings are in a run with a heat lamp & a dog house (the lamp is not in the house--there's no room for it inside). They've been there all night and are wet but don't appear to be uncomfortable. They want me to let them out to free range, but we will be gone most of the day so I have two choices: Leave them in the run, where it is cold and wet but they could go in the doghouse if they wanted to (but they don't seem so inclined), or put them up in the covered brooder under the lean-to. They would be cramped and unhappy in the brooder. But they would be dry and could get warm. Are they old enough to make a wise decision about staying dry and going in the doghouse? Or will they just keep getting wetter & colder & wonder why? Which would you choose?
