I have 2 Miniature Australian Shepherds I got when they were 3 months old.  I kept them on a leash giving the command "NO" when they even looked at the poultry/fowl.  It only took a few weeks and I was able to turn them loose and they paid no attention to the birds.  They are 3 years old now and I've never had a problem.  They became protective and let me know when there is a sound of stress outside in which case the 3 of us go running out the door.  I can leave Bear and Chase (neutered males) unattended ..... they will not harm my poultry/fowl.  Not sure how they would react with chicks.  They seem way to interested to test it.
