You can provide them with probiotics. However, a chicken cannot process dairy products, so a small amount of yogurt can be given. Otherwise, similar additives that contain vitamins, electrolytes, and lactobacillus acidophilus can be provided to improve gut health.

Worms 

Overload of intestinal worms can also cause gut damage, leading to diarrhea, so you need to check fecal samples to identify whether there is a presence of worms. If found, then treatment should be based on the type of worm detected. Follow the vet’s instructions carefully to eliminate the worms as well as cure the diarrhea.

Coccidiosis

Toxic Intake
