The tip above the chicken tail is the chicken tip, and there are chicken lymph nodes on both sides. The root of the tail of a chicken has a minute-long pimple called "chicken tip". Male and female chickens are available all year round. After the onset, the chicken's face turned yellow and white, its wings drooped, its food intake decreased, it stopped laying eggs, and it died after a week of serious illness. Treatment: lift the feather, disinfect it with alcohol, cut off one third of the "chicken tip" with scissors, and then squeeze out the yellow water by hand to recover.

You can also use a sterilized needle to vertically acupuncture the tail fat point at a small protrusion 3 cm above the tail tip until the acupuncture fails and twist it left and right several times. Keep the needle during the day, take it out at night and put it back in the flock for 2 days.
