So I understand that persin is the toxic element in avocado trees, and this toxin tends to be concentrated considerably in the leaves and bark of the tree. I have a small backyard, however I am planning to plant a dwarf avocado tree (either a Holiday variety or Wurtz) somewhat near to where the chickens are fenced. The tree will be planted about 6 feet on the other side of a fence where I keep the chickens. I expect that at some point in the future, the tree will grow enough to shed some leaves into the area where I keep my chickens. I expect to be pretty proactive with removing these leaves as they fall on the chickens' side of the fence, but of course, I can't be out in the yard 24/7 removing leaves immediately as they fall. Does anyone here know if the chickens will want to eat the leaves that fall to the ground on their side of the fence? I was under the impression that chickens possess a certain level of instinct and will usually avoid eating tree leaves that contain toxins (we also have an oak tree nearby that is already shedding leaves into the chicken's area, but I don't catch them pecking on oak leaves). Also, I don't plan on letting any avocados fall to the ground on their sided of the yard, and I don't plan on feeding any of the avocados to the chickens either. I'm just wondering if the presence of a near tree and falling leaves will present any danger to the chickens. Any advice would be appreciated.
