It totally depends on your dog and how it has been raised- I have a lab/shepherd/husky mix and she will ignore full-grown chickens, but if a chick runs past her wings flapping I think she just holds back the urge to chomp.
Dogs can get jealous, so tell the dog how good she is being when she does not misbehave around the chicks, as long as the dog thinks she is still #1 you have a chance. And of course lots of time and patience supervising. And positive re-enforcement NOT discipline!!!
heres a picture of my 11 yr old dog who has been around chickens and baby kittens lots and never maimed one.
