Avoid using any chemical pest controls and weed killers in your garden. Chickens will join predatory insects in helping to keep your garden pest and weed-free. Chickens like plenty of leaf litter beneath trees and shrubs in which to forage for protein-rich bugs, worms and insects. Trees and shrubs also offer them shade in which to shelter on hot days. On the other hand too much shade will not be appreciated, chickens like to sunbathe and love to take a dust bath in dry soil to help keep mites away. Access to drinking water is also a good idea – our’s share the dog bowls. Chickens will invade your beds and borders if they don’t have anywhere better to go. You may want to modify your planting according to what they eat and what they avoid – bit of trial and error here, certainly established evergreen shrubs should be okay. If you have an ornate, well-ordered garden then you may want to share only a part of it with your birds.
