I've not raised ducklings before. I just read a few post down that they need to be able to dunk their nostrils in their water. Why is that and what could happen if they can't? I just raised my ducklings waterer high enough that they really can't do that. They were making such a mess sloshing water everywhere. I thought this was best for the person who must remove the wet bedding everyday (Me!). If I need to lower it I will. I just don't want them to try to swim in it. Thanks for any advice.
