People created this problem by dumping than feeding, and protecting with no one taking ownership. What happens if you feed and take care of mixed sex animals they breed and increase .
now they have too many . Ive been talking to friends in florida they say the birds are not feral but very tame begging for feed and following you. When i lived in michigan, The local park had a program with us 4-Hers. in the winter we took home the pond waterfowl and in the spring we returned them .in those days people enjoyed feeding ducks at the park.
to answer you yes they will be removed, Being killed is not postive.
Wild muscovy will not be touched. Its the feral or tame ones that have no owner.
