I bet they will leave.

The migratory mallards that come to my pond they get mad at my Mallards because mine wont fly away with them. Also mine like to go in at night too, that makes the wild ones mad as well. So far mine have stayed here, they fly all around my farm, but that is all.

I think they will take off too and there are flocks of ferile mallards around- their mom's flock flew over the house yesterday. There are 4 of them. I was wondering if the ferile mallards (nonmigratory) ever migrate in the spring if they hang around with a flock of migratory mallards or do they remain here in Florida.
