Don't hit the inside of the leg. Because the main blood vessel nerve on the bird leg is inside, in this place the needle is easy to cause blood vessel, nerve damage, appear needle eye bleed, lame leg, paralytic wait for a phenomenon.
Don't use a thick needle under the skin. The needle of coarse needle is deep small, the needle is big, the liquid is injected hind easy outflow, and easy inflammation, bleed. Therefore, the subcutaneous injection, especially for injecting chicken with a fine needle, can be injected with a slightly thicker needle.
A needle in the chest cannot be pricked. When giving a needle to a young bird or a young bird, it is easy to Pierce through the chest because of its thin muscles, and the fluid can be penetrated into the chest, causing death. So, following the sternum direction, after the sternum is punctured next to the breastbone, the core of the needle will be pulled to the point where the needle is in the muscle, and then push the needle to inject the medicine fluid. Don't inject the same point at the same time. Because the muscle of the bird is thinner than the muscle of the pig, ox, if at a point to break into a lot of medicine fluid, easy to cause local muscle injury, also be adverse to the drug quick absorption, should take the medicine fluid to divide more points into the muscle.
