I might want to have a pretty big garden this summer so i was thinking that I would have to get rid of the weeds. Instead of picking them, could I just build an enclosure out of PVC or something like that with sides and a cover? That way i could just put them in there and let them take control of the weeds for me! If you have anything like this, let me know! Pics would be gladly appreciated! I have 12 hens but I would probably only make it big enough for 6 or 8 at a time! Thanks!! Cody!!
