That sounds great, I hope they take well! It sounds like you have a pretty cool setup, ducks, rabbits, biochar all doing their thing.
I don't do much seed propagation (yet) but my partner has charged me with taking care of the recently sprouted broccoli, leeks, and checkermallow. Soon I think they are starting potatoes to sprout, and judging by the variety of seeds we've got cold stratifying, probably a lot more.
