Oh good! I feel so negative when I tell people about it because my experience with [other peoples] dogs and chickens has been so negative.
I believe that introducing and forging a relationship between your dogs and your birds is a great thing, it just requires 100% supervision.
TBH, I came in the room one day and all three of my chicks [pre-dog attack] were asleep on the dog pillow WITH MY TWO DOGS! Lol. I wish I had had my camera at the time because it would have been a priceless photo.
But after the attack, I'm even paranoid to let my dogs wander the house with the chicks uncovered even when I'm there. It sucks, because I know my dogs would never touch my chickens [I think the fear of what I'd do to them is enough to stop them from ever hurting the babies] but this is because I force them to socialize.
My italian greyhound will sit next to their tub at night and peer in on them for HOURS at a time just checking on them, but I still would never let them be alone together. There's too much risk.
I wish you the best of luck.
What worked for me was petting the chicks and then rubbing my hands all over their toys and pillows, this way the smell of chick becomes something they smell all of the time, and not something that they need to taste and investigate further :D
