thanks very much
Yeah, ducklings should really be kept inside at that age and at that temperature. Do you have an enclosure you could keep the family in for awhile until the ducklings are older? Something with a nice house they can be locked in at night with warm, dry bedding out of the cold? If not, you could try to catch them and hand-raise them in your house for now, but of course it's always better if the parents can raise them. I just don't think Mom can keep them warm enough at this time of year to be out on a lake. Ducklings chill very quickly, especially when allowed out on the water so much like that. It's just too late in the season for those little ones to be out there.
