Hello! I'm not sure if this is the right place to post this question. If not, I apologise. I am new to chickens and my first chicks (Faverolles) are four weeks old now. I have settled on a movable coop and run system so they can tour all around my 10 acre property while being reasonably well protected from predators. My big concern is poisonous plants. I have been studying up on plants that are poisonous to chickens and which ones I have on my property. I'll go through each time I move the run and try to rid the area of these plants. But what if I miss one? Do they have any sense of what they shouldn't be eating? Is there any forgiveness in this at all, or if I miss one small hemlock seedling will they eat it and die?
