Ok, I'm starting to get concerned. I've been reading about plants and weeds and their seems to be a lot of things out there they can't eat. I have an outdoor pen and I've noticed Clifton eating a small plant/weed. I'm trying to identify the plant and haven't been very successful. Should I be concerned? Will these guys just start eating things that are bad for them? Do I need to remove all unfirmilar plants/weeds? I think it may be Buttonweed? I've also noticed some mushrooms popping up....oh boy, now I gotta be a botanist too?
