If you have chicks with coccidiosis, it could be passed to a puppy. Adult dogs aren't usually bothered by it. Their GI tract just pushes it out. my dogs love chicken poo too. it makes their poo stink, and might give them loose stool if they eat a lot.
Our girls free range and German Shepard got coccidiosis with our first group of girls. The girls got treated along with the dog and each time we introduce new girls we treat again. Our vet said it can live in your yard for over a year. So we reinforce, reinforce and reinforce again, the - "leave it" command.
One thing we do that may not be the best is we feed our dogs leftovers to our chickens.
