I don't have an actual house for my ducks...I have a bog white dog house, anyways for the winter time would that be okay? Of course I will put some hay in there for bedding... and possibly a heat lamp. We get some cold days where its 0 degreese or do I need to go build an actual house for them. Their will be four ducks living in there... ideally I'm trying to save up to build a HUGE chicken/duck barn in the spring.
