Hello! I have fallen in love with the Mandarin ducks and want to get a breeding pair or two. I am new to waterfowl or any fowl for that matter. I understand now is the time to have them shipped, but my duck pen isn't ready. Can they stay in a horse barn? Stalls are 8x10 with rubber stall mats. This would only be temporary. I'm hoping to have a 12x14x6 covered duck pen with concrete pavers around the pool. I have a kiddie pool for their "entertainment" but wonder about freezing in the winter. (I am in NC). Might put some pea gravel in as well. Any plants that you recommend? Also, besides a nest box, what kind of shelter should I have? Would a large dog crate work? Any suggestions or ideas are more than welcome and very appreciated!
