Will rat poison kill a chicken?

Rat poison can kill a chicken if it is ingested in sufficient quantities. Rat poison is typically formulated with anticoagulants, which can cause internal bleeding and/or dehydration, leading to death. The type of rat poison and the amount ingested will affect the severity of the symptoms and the likelihood of death. If you suspect that a chicken has ingested rat poison, it is important to seek veterinary care immediately.
