I planted chocolate mint in my run & my pullets scoffed it. It has recovered nicely & I have yet to find a new home for it. I'm now growing standard mint next to the run in the hopes that it will invade the run & not anywhere else. : ) I also have comfrey but have read that it's one of the plants to feed seldom to chooks or it causes problems. It's a pity because they grow such nice big leaves.
do you know what problems comfrey will cause? I have comfrey popping up around the run, along with mint actually, and they all love to munch on it...
