Hey everyone! I have 2 Indian Runner ducks who are 4 months old now, so this will be my first winter with them. I was just looking for tips/advice for the winter. Several people say as long as they have a shelter and water, you don't need to do anything extra. Then others say at least provide a heat lamp. One other question is when do you stop keeping a pool for them? It was down in the low 40s last night and when I looked out this morning...they were in the pool! Lol! I live in St. Louis, MO so winters aren't as bad as other places. Last year we had a few days with negative temps but not many. Thanks in advance for any advice!
