I have read through other thread about this, but have managed to confuse myself... I am waiting for three MyPet Chicken chicks to arrive in June.I also have three 1 month olds at home. As I understand it, I don't need to worry about the hatchery chicks infecting my flock, but should I worry about my flock infecting the new arrivals? My current chicks have been inside, are transitioning to outside this afternoon, no contact with other chickens. I have also not been to stores/places where poultry could contaminate my shoes (all on line, baby!). Any advice?
