I'm a newbie chicken mom, with three just about 2 week old chicks (RIR, Australorp (i think), & Barred Plymouth Rock) and one little over one week old chick (Blue Cochin). They've got a ways to go before they're big enough to go out in the coop but I am planning where to put it. Our yard has A LOT of creeping buttercups (http://www.kingcounty.gov/environment/animalsAndPlants/noxious-weeds/weed-identification/creeping-buttercup.aspx), which I've read are toxic to chickens, cows, goats, etc. I've also read that chickens are pretty good at avoiding stuff like that, but I'm guessing if it is in their run they will eat it sooner or later. If my husband and I remove as much as we can would that be sufficient? I imagine the girls will eat any new shoots that try to come back up. Or we could use Roundup or something like that but I'd like to avoid chemicals. Has anybody else dealt with this weed?
