  Dan has a flock of fine white Leghorn chickens. He takes care of them by machinery, for eggs are a crop, too. The hens live in cages with wire floors, so that they keep very clean. All their droppings go through the wire to a platform below. With a special scoop, run by his tractor, Dan cleans the manure from the platform and puts it in a pile to be used as fertilizer on the fields. Every day the chickens have their meals brought to them on a moving belt. The eggs they lay drop through their nests onto another belt that carries them away. Finally a machine sorts the eggs according to size, ready for packing. Some farmers raise chickens for the market. Of course, the feathers must be taken off after the chickens have been killed. There are machines for this, too. One |
