Here in Virginia--Chickens and turkeys are raised by the billions Yes with a B. So much so the Va Tech's mascot is a turkey and the local HS sports team is known as the gobblers.
Raising chickens is dirty, smelly, nasty work---up at dawn in bed very late. Profits not so great--
many of my neighboring farms are doing chickens---a quarter mile from my home is one--every once in a while a country smell comes thru the air --and my eyes water.
I wanted to be a farmer, still raise over 1/2 acre of veggies, etc and many fruit trees---I wanted to be a farmer until I found out it was work, lots of work, lots of dirty work--sick animals, sick plants, sick trees--bugs of every kind. ---I just love farming--in the grocery store.
I lived on an old time farm as a kid--shoveling out stalls, hand milking, feeding---no vacations--the animals come first. If you are a big time super farm manager--maybe that's good.
