I have some chicks in a brooder now, they will be out in a couple of weeks. In preparation for their "big move," I've been clearing out a couple areas in the yard for when the girls can finally can go free range, even only for a few hours a day. And welcome spring with all its glorious weeds!!!! lol We have an overwhelming plethora of Bermuda Buttercup (Oxalis pes-caprae). All over. Everywhere. Ugh. And according to this list, http://www.poultryhelp.com/toxicplants.html#V, Bermuda Buttercup is considered toxic to chickens. Just how toxic? (Is that a stupid question?). Do I need to excavate my entire property? Impossible. It would be easier to give up my girls (not really). Or just clear out a few spot areas and keep the girls on a "tight leash?" This weed is pervasive during spring and pops up practically overnight, continuing it's procreation well into early summer. I will never completely get rid of it, but I'd be heartbroken if something happened to any of them that I could have prevented.
