To get them into MO, from their website: "Many states, including Missouri, require either a negative pullorum test within the past 90 days or participation in the NPIP for poultry to legally enter the state or be exhibited at public exhibitions (2CSR 30-2.40)."
http://www.mda.mo.gov/ah/poultry.htmI would contact them at the numbers provided on the page. They are easy to work with and will hlet you know all the steps you need to take.
There are no requirements for a permit to keep & breed this species in Missouri. What part of the state are you headed to?
