I am trying it, but not with meat birds, we only have a small layer flock of about 30 birds. I do want to try it with meat birds soon and will be raising dark cornish instead of the hybrids. What I did to cut labor was to construct a small holding pen that opens off the chicken house. 3 large pasture areas are joined to the holding pen. I can switch the birds from area to area just by opening and closing some small "gates". This works like rotating pastures with my sheep flock. So far it's working great. The birds pick an area down in about a week. They aren't on that area again for 2 weeks and it's grown back up by then. The down side was investing in all the fencing, but I am using the cheap 4ft tall black plastic netting available at Lowe's. $25.00/100ft. I put a line of electric tape along the top and down low on the perimeter to keep my sheep from pushing on the net and keep out chicken eatting critters. None of the birds have yet to fly out, but they are large heavy layers and 4 ft would be a bit much for them. If any do, I'm going to clip wings.
What kind of birds are you raising? Do you purchase the hybrid chicks? I have always wanted to try breeding the hybrids but can't find any of the white cornish standards to cross with white rocks. Has to be done AI, but found a web site on it and sound pretty easy, at least compared to the other AI's I've done...

We do it with no problems. We got lucky and found 3 huge roles of bird netting at a local thrift store for fencing. If you are doing meat birds you probably won't even need it as they grow so fast and large that they can't fly anyway.

Was trying to locate the book I hade purchased awile ago to mention to you .. for a reference,and then I noticed they have it for sale on this site ..check out the home page. we use the poultry netting and it worked great. Good luck

Sam,
The main folks doing pastured poultry here in New Mexico is Pollo Real Ranch, Tom Delehanty and Tracy Hamilton. They have been doing this for some time and are very successful. They are probably full of info on the subject. Call 505-838-0345.
Wishing you the best,

Yes, We raised pastured broiler chickens for three summers. Yes, it is alot of work. We did not use the tractors (portable shelters or low coops on wheels), so we were not moving them every day. We put them on an area where we could use or rototill in all their waste. Each batch was in a new area. I paid myself $10/hr and tried to keep the time commitment to an average over the six weeks of less than one hour a day. The huge work load was the butchering and processing. I added a flat processing fee of $2.50/bird on top of the per pound cost of the birds. The final cost of each broiler came out to about $13.00 -15.00 for a 4.5 - 5-lb "broiler". I had no difficulty pre-selling them. I had a nearly impossible time finding workers to butcher and clean the birds. We have no local small poultry processor; my husband and sons have gone on strike; and the area farmworkers have not been interested for just $10/hr. I keep hearing word that there is a group working on financing an small-scale poultry processor. Can't wait.
