Hello everyone! I am a first time duck owner and my two males Mario and luigi keep trying to eat this bush. I don't know what it is and I'm nervous because I know some flowers are poisonous for ducks. I mean they already ate some so if it is poisonous there's not much I can do. Im just wondering if I should keep letting them eat it. I put a fence around it for now. Any one have any answers or can send me in the direction to find out what it is? Sorry for the trouble your the best!!
