I would be concerned about spreading any feces from meat-eating animals. That encourages maggots and introduces harmful bacteria to the soil. The nitrogen-rich manure of plant-eating chickens, though, is great for composting.
“Composting” to me means combining the right proportions of brown material (dried leaves), green material (grass clippings), kitchen waste (vegetable scraps, coffee grounds, eggshells), and chicken manure to make rich, dark compost for enriching and aerating garden soil.
