This here's a big white hen chicken mama gal of mine, done by  Voicelessfreak!
I'll call her Chelsea.

Chelsea is one of the servant trainers, or "big mamas" over at Farmer's Fannie's Farm. She teaches the new servant employees how to conduct themselves around visitors and each other, the do's and don't of servant work (explaining that there shouldn’t be any direct mating between servants and visitors, for example), the different ways to clean a room as well as clean themselves and each other, and how to perform specific tasks expected by specific servants. She personally trained Milly and Oliver on how to handle their milking and mounting services and is proud of it. Chelsea also provides personal advice, care and affection to any servant in need of it. "Don't be afraid to holla' for mama!" is one of her famous sayings, since she has gone and stopped most past incidents from either occurring or getting worse because she was able to offer help and support when it was needed the most.

Chelsea obeys her superiors as well as she can, but she also truly cares for the servants she trains. While she plays most things by the book, there have been made exceptions to offhand behaviors or small situations based on what she considers the best or simplest choice for everyone involved.

She's also not actually a mother, but she doesn't mind being called one inside or outside of work.
"If it makes you happy to say, it makes me happy to hear! Mama's here for you, and don't you forget it!"

She does have a few nephews and nieces, though. Loves seeing them when she can!

Chelsea's age is 35, with a height of 6 feet.
