Chickens love eating plants! Grass, leaves, flowers – they’ll eat everything leaving your yard bare if they like what you have growing.
A rule of thumb that we go by when selecting plants for our yard is to select those that are deer-resistant. We have lots of deer in our area, but also have a fully landscaped yard that the chickens don’t bother because they’re all deer-resistant. We are in gardening zone 5, and are currently enjoy pachysandra, vinca, bluebells, bleeding hearts, pulmonaria, forget-me-nots, geranium, daffodils and various Spring ephemerals.
Your plant nursery or online source for plants will usually indicate if a plant is deer-resistant. You can also Google “deer-resistant plants for zone [your zone] or [your state].”
While chickens might eat anything if they’re hungry or bored enough, selecting plants that deer won’t eat may be your solution to keeping chickens and a beautiful garden.
