I only know of duck haven near Miami and the owner is elderly and overwhelmed.
I don't know if the duck could be sent in a pet carrier by Amtrak from Miami to Palatka. If it can, then I would pick him up from Palatka and look after him prior to rehoming.
I don't as that boy is a house duck and folks I know who rescue have backyard flocks or duck sanctuaries. My Daffy would never forgive me if I let another duck live in my house and made him stay in the coop with "ducks". Daffy thinks he should be a house duck!
