I have someone wanting to buy a pair of Cayuga ducks from me, But they in in the Czech Republic, they say they have pair air transport, but is it legal for me to send them from the country? I know nothing of shipping birds either, any help I can get on this I appreciate!! They also said if its sending to a friend I need nothing, and if they don't know the terms of trade its fine. I am just feeling something fishy about this.
