Please be especially watchful of your dog. Dogs tend to regard chickens as squeaky toys. They chase and catch them. As soon as one stops squeaking (DEAD) they drop iand run for another. They can wipe out a flock single handed, in the blink of an eye. Whether they are playing or not the result is DEAD chicks/chickens.
Chickens are not meant to be herded like cattle or sheep and have no heels to nip at. They will panic and squawk and flap wings trying to escape - that only excites the dogs even more.
Chickens need a protective dog that will drive away predators or eliminate them. Good luck
