This is my first official post but I've been reading threads for about a year now. We have three remaining hens after our dog started attacking them so now we have to keep them separated all the time. They don't much appreciate this after their wide free ranging. I'd like to plant some bushes on the side of the house where they are confined for a lot of the day to offer them extra shade and protection in the hot Phoenix summer coming up. Last year we planted a couple of different kinds but they ate them when they got bored and couldn't go foraging anywhere else. I'm wondering if you can recommend something they won't eat, that's not poisonous to the hens and that can tolerate a lot of shade but also a lot of heat? Thanks!
