22 Common Chicken Diseases And Treatment

1. Newcastle disease

Symptoms

The chickens suffer from depression, loss of appetite, panting, breathing with mouth open, eyes closed, yellow-green or white sparse discharge. You may notice the crop is full of mucus, and a large amount of sour and smelly liquid is poured out. The cockscomb and wattle are dark red or blue-purple. For laying hens, the laying of eggs dropped rapidly, the eggshell was milky, rough, and deformed eggs and soft-preserved eggs appeared. Later neurological symptoms appear, such as ataxia, spinning in circles, twisting, head touching the ground, or looking up at the sky. Atypical Newcastle disease is characterized by difficulty in breathing, sporadic death of chickens, green feces, decreased production performance, and neurological symptoms in some cases.
