Can chickens eat rhubarb? Noβchickens should not eat rhubarb leaves, and even the stalks should be treated with caution. Rhubarb contains oxalic acid (oxalates), a natural plant toxin that can bind calcium and damage organs, especially the kidneys.
While the stalks have lower toxin levels, the leaves are highly toxic and can cause serious health problems or death in chickens.
If you raise backyard chickens, understanding which parts of rhubarb are dangerous, how toxicity works, and how to protect your flock is essential for maintaining a safe and balanced poultry diet.
Why Rhubarb Is Toxic to Chickens
Rhubarb is widely known as a toxic garden plant for chickens, mainly because of its high oxalic acid content. This compound is naturally found in many plants, but in rhubarb leaves, it exists in dangerously high concentrations.
How Oxalic Acid Affects Chickens
- Binds with calcium in the body
- Reduces calcium absorption
- Leads to kidney damage and renal failure
- Disrupts normal digestion
Scientific estimates show:
- Rhubarb leaves contain about ~0.5% oxalic acid
- Toxic exposure can occur around ~375 mg/kg body weight
βOxalic acid doesnβt just irritateβit interferes with essential body functions, making it dangerous even in moderate amounts.β
π This is why rhubarb is listed among toxic plants for chickens.
What Is Oxalic Acid? (Simple Explanation)
Oxalic acid is a plant defense compound. It protects plants from pests but becomes harmful when consumed by animals.
In Chickens, It Can:
- Bind to calcium β causing deficiency
- Form crystals in kidneys β causing damage
- Trigger digestive and neurological symptoms
The highest concentrations are found in:
- Rhubarb leaves
- Roots
- Certain other plant parts
