One of the most common questions from backyard flock owners is: can chickens eat onions? The answer is no—onions are not safe for chickens. Onions contain compounds called thiosulfates, which can damage red blood cells and lead to a condition called hemolytic anemia in poultry. This can cause weakness, reduced egg production, and even death if consumed in large quantities. While a tiny accidental bite is unlikely to cause harm, onions should never be given intentionally as part of their diet.
Instead, stick to safe fruits, vegetables, grains, and protein-rich treats like mealworms. Just as diet plays a role in flock health, so does proper housing. A secure, well-designed coop is essential to keep your chickens happy and safe. Let’s look at the best options available.

Buyer’s Guide: Choosing the Right Coop
Just as you avoid feeding unsafe foods like onions, you should avoid unsafe housing setups. A good coop should have:
- Space: 3–5 square feet per bird inside the coop.
- Predator Safety: Use hardware mesh and secure locks.
- Ventilation: Fresh airflow keeps bedding dry and reduces disease.
- Cleaning Access: Wide doors and pull-out trays make chores easier.
- Weatherproofing: Protects hens from heat, rain, and snow.
- Nesting Boxes: Provide clean, private egg-laying areas.
