IMO, anyone growing hay really would prefer that it not be full of chicken crap. I know that is how I prefer it. As far as wheat. barley and oats, the damage they would do SO wouldn't be worth any possible small benefit.I'm looking at production quantities, for meat birds or eggs. Hundreds of birds, possibly. Though would start on a much smaller scale.
I free range roughly 40-50 layers year round on my 3 acres and have access to 40+ acres of fallow field that gets brush hogged every year. I fence them out of our 1/3 acre garden. I have read some studies where people have grazed chickens in rotation with cattle, sheep, goats and other such critters, but I was more interested in raising poultry on crop land. Hay seems to make the most sense. It gets cut several times a year, chickens would eat it and the bugs that eat it and fertilize the soil at the same time. I know that where the chickens seem to gather in my lawn the grass grows faster than they can keep it mowed down. Actually making it so prolific that I need to mow those areas more often than the areas that they tend to avoid. I have turned them out in my sweet corn patch after the corn grows to be about twice their height, and they seem to keep some of the weeds down, but feed consumption is on par with hens in confined pasture. I purposely plant raspberries in my open top confined pasture, to help with protection from flying chicken eaters. The berries do very well, and yield about 50% more than the berries that are outside of the pasture. The hens don't really seem to go after them until they are completely ripe. By then I rotate them to a different pasture in order to harvest. But again feed consumption seems on par with pastured hens, maybe even higher. I assume due to the lack of grass under the shading berry bushes.
I believe that some crops would benefit from having the chickens patrolling constantly. Most hay crops would benefit from the nitrogen in the manure and the pest control offered from the roaming flock. Would the benefit outweigh the damage done by the birds feeding and roaming around trampling down the crop? How about crops like wheat, barley or oats. Could a flock possibly benefit a crop enough, in terms of pest/weed control and fertilization, as well as offset cost of commercial chemical usage for the same purpose to make it worthwhile doing?
