What are the pest control methods for raising free-range chickens in orchard mountainous areas?

When raising free-range chickens in orchard mountainous areas, the relationship between pest control and grazing must be handled properly. Generally, there are fewer pests in orchard mountainous areas where chickens are raised, but when pest control is needed, first choose pesticides with high efficiency, low toxicity and low residue, and try to spray as little as possible onto the ground, so that even if the chickens eat the insects, the possibility of poisoning is small; second, choose sunny days for pest control, so that less of the pesticide solution drips onto the ground. It is best to stagger pest control and grazing times, so that the chickens come into contact with the pesticide as little as possible, just to be safe.
