There is a wide swath of Four O’Clock flower plant in my yard. The seeds are ripening and falling on the ground. Some of my chickens were eating them this morning. I am reading that the entire plant, including the seeds are toxic to people and animals. They all seem to be fine at the moment, but it has only been a couple of hours. Has anyone had actual experience with their birds getting sick from these seeds? And what can I do to help them?
