We have 2 "chicks" who are about 10 weeks old. They spend their days roaming our small fenced backyard. Our 2 dogs protect them there. However, our dogs are also indoor dogs who enjoy spending time on our couch when they're not on guard duty. I'm concerned that they are lying in chicken poop outside (although they appear clean of course). I am 7 weeks pregnant. What should I be concerned about catching from our chickens, via our dogs? My hubby plans to build a chicken tractor, so our dogs won't have to spend as much time outside protecting the chickens, and the chicken droppings will be a little more contained.
