I have 10 that are on the pond. No biggie, right? Well, the pond froze last night, it usually doesn't til like January, but it has been so dry this year that the water level is low. I have no problem leaving them out there when they have water to escape to, but if it is frozen that makes them (excuse the expression) sitting ducks to predators!! We haven't had any problems with predators, other than hawks, but winter is coming, and we only have one dog Well one that is loose and will keep predators away. Anyway, the ducks are pretty wild, and I don't have a net or anything. I was thinking of trying to 'bribe' them up by the house and putting them in the barn. Any suggestions??
