I believe it's possible to come out on top financial wise with chickens. Firstly- Yes, you would need alot of birds, land and upfront feed cost. I live in MD and know a woman who does... she is not rich by any stretch but has a suffient business. She has a small family ran butcher business ... she sells eggs and charges $3 per lb for her birds and then an additional butchering fee. However, She also raises lambs for butching. MD has little to no butchers ...i had to search hard to find her...however when i was there getting my birds butchered, she had a booming business ( at least 12 people came in while i was there, Ordering whole lambs and multiple chickens). Just saying its work but it is possible.
