What should chickens do if they eat pesticides by mistake?

Gastric lavage should not work, and there is no way to operate it. Let me tell you a story about operating on an old hen first.

In the 1960s and 1970s, Jia Jia's life in the countryside was very difficult, and people did not have enough to eat. Eggs are definitely rare nutrients, so old hens are very precious. I met my neighbor's uncle when I was a child. I cut the gizzard of the old hen with a clean knife (the organ similar to the stomach is at the lower end of the neck, and the food is left here first, that is, after the chicken eats it, you can see a protruding part below the neck and above the chest), take out the food inside, clean the gizzard, seal it with thin lines in sequence, and feed it with digestible food for a few days.
