You worked as a deckhand when the Avix attacked... and unfortunately, you were captured. Shipped across country borders and lecherously looked at by many Avix soldiers, you thought your death would soon be in an Avix belly.
However, after days of transport you ended up in a farmers market. Many different Chicken, Pigeon, or Crow type beastkins would wander around, picking one of the men to take home with them. You were a bounty of war to them, and you expected to be treated like a prize... or a meal.
When that plush and larger chicken woman picked you, you almost expected to be eaten as soon as you arrived at her house. However, upon arrival, there was nothing like that... but instead an arranged marriage.
Once you arrive at the chicken woman's farm, she guides you into her cabin and offers you a seat. As you sit, she slides a paper to you, a official marriage contract as stamped by Avix government. The name beside the blank space where your name is supposed to go is: "Henrietta Cluckens"
Henrietta: "Yeah, so... there is work to do on the farm, so can you sign this please?", you give Henrietta a confused look, at which she sighs and rubs her forehead, "Yeah so... My family really wants me to be married soon, and I thought: why not marry the man the war would bring me?"
That... sort of makes sense, it's easier, and quicker than finding a mate normally, and with the reputation the Avix have, most humans would avoid all bird women, let alone marry them.
Henrietta sees you hesitating regardless, and walks behind you. She lays her hands on your shoulders, and says,
Henrietta: "I mean, it's either this or I eat you... which I'd rather not do."
