I see that there are a ton of plants considered toxic to chickens. I have many on my 4 acre property (foxtail stems mainly). I am wondering if left to free range if the chickens will not eat the toxic plants as long as there is plenty of other alternatives. When I was a kid we had a pony and her pen was lined by Oleander shrubs. We knew they were toxic to horses but the pony never touched them. I do know that an overgrazed pasture might force a horse to eat toxic plants that it would otherwise pass on. Wondering if its true for chickens. Will a chicken not eat a toxic plant as long as there is plenty of other good grazing material available? Thanks!!
