Whether or not a chicken can die from a bite is a complicated question that depends on the size, severity, and location of the bite. A chicken can die from a bite if the bite is severe enough to cause significant blood loss, damage to vital organs, or infection.
Small bites from other chickens or animals, such as cats, may not be fatal, as long as the wound is treated promptly and the infection does not spread. However, larger bites from larger animals, such as coyotes, can cause severe injury or death. If a chicken's crop is punctured, the bird may become weak and unable to eat or drink, leading to death.
In addition, some parasites, such as mites, can cause serious injury to a chicken if they are allowed to feed on the bird's blood. If a chicken is infested with these parasites, the bird may become weak and unable to eat, leading to death.
Ultimately, a chicken can die from a bite if the bite is severe enough and if the wound is not properly treated. It is important to monitor chickens for signs of injury, and to seek veterinary care if necessary. If treated promptly, bites from other animals or parasites may not be fatal.
