I do not restrict my meaties feed much at all. When little, they get food 24/7, then I fill the troughs and keep them basically full during the day. They do have times with no food just because I didnt get back out to them right away. I do not fill it for the night, but will make sure they get a full trough close to evening so they dont go to bed empty. There is usually a little left when I put them to bed. I have a tractor and let them free range during the day (they are in a fully fenced yard). They do pretty well even at 8 weeks old when some of them are 8+ lbs. I have a lot of shade, so while they are uncomfortable in the hottest weather, in the shade and able to separate during the day outside the tractor, they handle it pretty well.Thanks, all. Right now they're a week old. I'm just keeping food in there all the time and letting them eat as they'd like. I'd like to move them into a chicken tractor as soon as I feel they no longer need the heat plate. My concern is that it's really hot, even here in NH, during the day.
I may go to the 12 on 12 off feeding schedule, but putting them to bed on an empty stomach seems unnatural for chickens.
My plan WAS to make an 8 x 10 tractor and cover the last 4' top and sides and move it every day or so. I have 25 birds. If they do well in the tractor and get crowded, I may let them pasture. I really don't know. I've only raised layers.
I guess I just have reservations about restricting their feed. Everyone has different advice.
You will find what works for you. I did make the mistake of feeding a lower protein to my 1st set of meaties this year and they were small-when I realized they werent growing, I kept their feeder filled. The next 2 sets grew as expected on the higher protein food.
