Plants poisonous to poultry - The Accidental Smallholder

Poultry can be susceptible to poisons, including certain common plants. These include:

• Black nightshade
• Castor bean
• Clematis
• Corn cockle
• Henbane
• Laburnum seeds
• Meadow buttercup
• Most irises
• Oleander
• Potato sprouts
• Privet
• Ragwort
• Rapeseed
• Rhododendron
• Rhubarb leaves
• Some fungi
• St. John’s Wort
• Sweet pea
• Vetch
• Yew

Fortunately, most birds will avoid these plants by nature.

Blue-green algae can be quickly fatal, so don’t allow access to stagnant water and ensure that water containers are kept clean, especially in hot weather.           

Obviously, chemicals such as rodenticides, herbicides, fungicides and insecticides will generally be bad for birds so keep them safely locked out of harm’s way and used with care, if you must use them at all.
