Why do 4 hens pick on one hen?

There are several reasons why 4 or more hens might pick on one hen. Some common reasons include:

- Social hierarchy: In a flock of hens, there is a social hierarchy, with some hens being more dominant than others. Dominant hens may pick on subordinate hens to establish their dominance or to gain access to resources such as food and water.

- Boredom: Hens that are bored or lack mental stimulation may engage in aggressive behaviours such as picking to alleviate their boredom. Providing a variety of activities and enrichments can help to prevent boredom and reduce the likelihood of hens picking on each other.

- Crowding: If there is overcrowding in the flock, hens may become stressed and more likely to engage in aggressive behaviours. Providing adequate space and resources for all hens can help to reduce stress and prevent picking.

- Health problems: Some health conditions can cause hens to become more aggressive or irritable, leading to picking. If you notice a hen that is being picked on and displaying signs of ill-health, it is important to consult a veterinarian to rule out any underlying health issues.

- Personality: Some hens may simply have more aggressive or dominant personalities, which may make them more likely to pick on other hens. If you notice a particular hen that is always picking on others, it may be necessary to separate them from the rest of the flock.
