Keeping Backyard Hens Safe

When we think about keeping our backyard hens safe, we look at housing and fencing to protect them from predators. But what about common plants that can be harmful to hens? With appetites for anything they can get their beaks on, it’s important to ensure poisonous or harmful plants are not growing in their midst.

The helpful plants are natural insecticides that help reduce mites and lice that otherwise may cause health problems for chickens. These plants should be placed outside the chicken’s range, so they are not eaten by the hens but can offer protection.

Natural Insecticides

In terms of plants and tress to place around—not in—your coop, consider these, which have natural insecticidal properties.

These plants aren’t good for your chickens to eat, but they may prevent the forward-march of mites or lice toward your flock.

Chrysanthemums Chrysanthemum morifolium	Bay laurel Laurus nobilis
Neem tree Azadirachta indica	Lavender Lavandula angustifolia
Tansy Tanacetum vulgare	Artemisia Artemisia vulgaris
Comfrey Symphytum officinale

Poisonous Plants

Finally, let’s look at poisonous plants. Because they’re often difficult for the average homeowner to identify, we recommend consulting your local extension agent or master gardener. Keep in mind that seasonal seeds, pods, or acorns—which you may not see at the time of year when you’re readying your coop—can pose risk, so plan ahead when you are choosing a site for your coop.

The toxicity of these plants may be restricted to their seed, a particular part of the plant, or a stage of growth, so read up before landscaping with some of these plants. It’s not necessarily the first bit you should worry about, but rather chickens consuming larger quantities over time.

Shown here are some poisonous plants to remove from your yard.

Foxglove Digitalis purpurea	Nightshade Atropa belladonna
Oleander Nerium oleander L.	Black locust Robinia pseudocacia L.
Bladderpod / badpod Lsomeris arborea	Castor bean Ricinus communis
Corn cockle Agrostemma githago L.	Crown vetch Coronilla varia L.
Death camas Toxicoscordion veneeosum	Jimsonweed / thorn apple Datura stramonium
Milkweed Asclepias syriaca	Poison hemlock Conium maculatum
Pokeberry Phytolacca Americana	Water hemlock /cowbane Cicuta maculata
Yew Taxus baccata

and Rattlebox Crotolaria verrucosa
