An advantage to freezing sperm packets is that after you get to where you're going, if you need better foraging birds you could slip some game bird sperm packets into the hens and cross things up a bit. If your birds got too flighty, or too thin, you could inseminate with Orpington sperm packets to get a larger more stable bird.
With frozen sperm you could make sure your gene pool never got stagnant.
