It depends on the type of poppy seed. While some poppy seeds are relatively harmless, others, particularly those from the Mexican poppy, can be toxic to chickens.
Here's a breakdown:
-
Opium Poppy Seeds (Papaver somniferum): These are the type of poppy seeds commonly used in baking. While they contain trace amounts of opioids, the levels are generally considered safe for chickens in very small quantities. However, it's best to avoid feeding them these intentionally. Large quantities could cause problems.
-
Mexican Poppy Seeds (Argemone ochroleuca and Argemone mexicana): These poppy seeds are toxic. They contain isoquinoline alkaloids that can be harmful to chickens.
- Effects: Consumption of Mexican poppy seeds can cause stunted growth, fluid retention, and even death, especially in young chickens.
Recommendation:
Avoid feeding your chickens any poppy seeds, especially if you're unsure of the source. It's simply not worth the risk. Ensure wild Mexican poppy plants are removed from areas where chickens roam.
In summary, while trace amounts of opium poppy seeds are unlikely to cause harm, it's best practice to avoid feeding any type of poppy seeds to chickens, and absolutely avoid any seeds from the Mexican poppy varieties due to their potential toxicity.
