I want to plant another shrub in the chicken run, ideally something they're not going to eat. I have forsythias right now, but their bottom couple of feet are naked as the hens have eaten everything they can reach. I read somewhere that chickens don't eat viburnum shrubs, but that's a very large and diverse group of plants. So I was wondering if anybody had any experience with shasta viburnums specifically. I'll put chicken wire around the new plant to protect it, but when it eventually branches out, I don't want the chickens jumping and plucking leaves from it...
