I have been keeping my ducklings inside due to clod weather ( I live in nc) but there starting to stink up the whole house! I put them in the garage tongiht with a heat lamp and a heater beside of there container. Went to check on them and there shivinging in the corner cuddled up. They were in a small storage room the heater heated up the whole room. There 2 or 3 weeks. I use a plastic storage container with puppy pads and a towel and clean it every day. Not sure what to do here. Most people keep them outside so why can they stand it?
