We just got some baby ducks a couple of weeks ago. They are probably 5-6 weeks old and my husband and I were wanting to put them outside during the day. Would this be ok to do if they were in a fenced in area? Also I'm assuming they would need to come in at night? We live in Columbus Ohio and it still gets cold at night. We have a pond that they can eventually go to but they don't have adult feathers yet. Also does the fenced in area need to be covered to keep predators away? Thanks for your help!
