Hello I'm a writer and I've come upon your forum doing research. I have a couple leaving Philadelphia in 1854 and going to the Montana territory by way of Saint Louis and the Oregon trail. What kind of chickens would they take, and most of all how would they transport them? In the wagon? In a pen? The wagons only move at 2miles/hour - would the chickens stay with the wagon if let free? do they have to carry feed or can the chickens eat off the land? Thank you very much for your time.
