I read an article about feeding chickens and this is a big help when our outdoor greens start to fade. Weeds! As soon as I heard this I went outside and pulled a nice big one, do not shake the dirt off, it is full of lovely bugs and other goodies they forage for. The first time I did this they went nuts and ate everything from the dried leaves to the roots, it took them about 20 minutes to clean it all off. The only thing left were the stems and large roots. Free food, yeah..... Any other suggestions of what you feed your guys that is cost effective?
