The dogs should keep away predators.
Do your dogs get along with chickens?
Two of them have been around chickens before one hasn't. They are shelties.
At our old place I rented, we had chickens visit from the neighbors house down the street. The dogs didn't care one bit..No aggression at all although... my wife would herd the chickens with our male. Kind of funny..but again, no agression..he would just get in front of them and cut them off or drive them where my wife wanted them to go...My wife is a chicken herder..LOL..
Our 1 year old puppy may be a problem though. She has a strong chase / herding instinct and she goes after sparrows and other birds that land in the yard...She may be on a leash for awhile...
