Backyard flock owners are often surprised to learn that chickens are natural omnivores. This leads to the common question: can chickens eat mice? The answer is yes — chickens can, and often will, eat mice if they catch them. Chickens naturally chase and peck at small animals, including mice, frogs, lizards, and even small snakes.
Mice are rich in protein and fat, which can benefit chickens, especially during molting or egg production. However, there are risks. Wild mice can carry parasites, diseases, or poison from bait traps, which can harm your flock. For this reason, while chickens can eat mice, it’s not the safest protein source. In this guide, we’ll cover the pros and cons of chickens eating mice and the best safe alternatives.
