the breed really doesn't matter. Dogs think that chickens are toys. They run, make funny noises, flop all over the place. POUNCE. Bird is crushed, but there are 5 more still running around so on to the next one. Some dogs will never bother the birds, others will stop at nothing to get to them. Some will just drool on them, some will chew on them. A few will even actually eat them, but not as many as you would think. Most just play too rough and then drop them when the toy is "broken"
Ask your neighbor to help you. Start now when the dogs are pups and teach them to ignore the birds. Just a few minutes of work every day and you will know that your birds are safe. Put the dogs 1 at a time on leash and take them to where they notice the birds. Tell them "leave it" and give a pop on the leash. The second they look at you, say "YES" in a happy voice and give them a treat. Once they are comfortable at this distance, then move closer. If they lose interest in you and focus only on the birds, back up and start again. Eventually, you will take off the leash. The goal is that the dogs just ignore the birds. You don't need to make the dogs afraid or to avoid the birds.
Of course, this is going to take cooperation with your neighbor. He needs to make sure that the pups are kept confined, otherwise they will discover the chickens on their own. Of course, if he is responsible, he will already plan on keeping them confined. The easiest way to train good habits is to prevent the bad ones.
Since these are puppies and don't live with you, I would work with them on occasion, even once they are reliable. Since they are pups, they are going to go through phases of disobedience like any kid. Periodic training sessions will help keep them on track. Once the dogs are about a year old, then they will be pretty reliable.
