Are daylilys safe for chickens to eat? What about evergreens? Are there poisonous plants (can I go by the list I use for kids/dogs, or is it something different?). I'm asking because Hubby is concerned that our chicken coop screams CKN COOP!!! the second you pull in the driveway, so I'd like to screen it with some plants.. but don't want to poison the chickens in the process!!
