I have been raising them for awhile now. They start off in a wooden box for approximately 2 weeks (1 week with a light), then out into the tractor for a couple of weeks. Everyday morning the tractor is moved to a new location. I have tried something new last year which I will do again. After the 2 weeks in the tractor, I'll put up the poultry fencing and use the tractor as a "coop" for them. For the last 4 - 6 weeks, they'll be in the netting area.
As far as the feeding, the first week they have food in front of them for 24/7. After the first week, they have food for 12hrs, then I remove it for 12hrs. I do the ~6AM to ~6PM without food, and ~6PM to ~6AM with food. And yes, they do eat at night, the bin has always been close to emptied in the morning. They also get table scraps and forage (in their pen area) in the daytime. I am always adjusting the food quantity so as not to waste it, but to make sure they have enough. If in the morning there is alot left, next time I add less. If it is bone dry, I'll add more next time.
They get fresh water 2 -3 times a day.
