I have 2 ducklings that are around 4 weeks old now. This is the first time I have gotten ducklings during cold weather. Right now they are in my bathroom but even changing there bedding everyday they are stinking our bathroom to high heavens. The current weather for our area, southern maryland, is low 50's to 30's at night. My question is will they be okay outside in the shed? I have a heat lamp I can put up for them put there.
