I just ordered my chicken coop..yey! However, i am trying to figure out where to put it. I have the space but cant figure out where to put it. Is it a big no no to have concrete as part of the run? I mean I have enough lawn but on the other side of the backyard i have more concrete than dirt...i can alwaays jack hammer through it though, but before i do that...what do you guys think about it???
