I'm a total newbie. Don't even have the incubator built yet, but am doing all my research first (that's good right?). We live in suburbia, have a nice sized yard, and have two large, well behaved dogs. Do dogs and chickens ever mix? Will my dogs constantly try to get into the coop? Will they ever all roam free together? And most importantly... what if I miss a dog poop on the grass, will the chickens eat it while free range? Just want to make a plan before I pull the trigger. Thanks!
