so my one female laid a clutch of eggs not to long ago and well they hatched on December 31, 2015. It's getting cold here in NJ (20-50F) and I'm not sure what to do with them. The mother duck left two behind which I was able to rescue but there are three more with her. She nor my goose will let me near the remaining ducklings. Should I leave the ducklings with her or try to get them and bring them in?
