I have one of each!
Lab/husky x is GOOD braving his fear of scary noises in the dark to charge out valliantly at 3 AM on several occasions to chase a raccoon off our hen who used to hide in the bushes at night. He WILL steal scraps of food from them, but he'd never hurt one. We used to have a gimpy chick...barred rock roo with something wrong with his legs so he couldn't really walk and we found Loki one day laying down with him, just licking the poor thing's back. From the level of wet he was, I would guess L

ki had him for about half an hour. He was trying to make him feel better! We also had a house chicken for a bit (the lone hatchling from our incubator who was allowed to roam the house with cat and dog from the time he was 1 1/2 weeks old) and Loki actually let him eat some of the tablescraps.
Lab/golden retrieverx is BAD killed 2 hens, 1 chick, and 4 pullets (two of which he ATE) as well as wounding 6 more chickens (at least one of them twice, my poor roo!) all of whom fortunately recovered, though one of my hens has a visible disfigurement- her neck feathers grow in funny on one side giving her the appearence of having a jagged line of feathers plucked out from her wattles to her breast.
You better believe my birds can tell the dogs apart, too. My Loki comes up and they make the same noise they do for the kids or the room mate who doesn't usually feed them. Sort of a 'Oh, someone's coming but no need to follow them/run from them' sound. Apollo so much as LOOKS at the fence and they screech this 'EVIL MURDEROUS HELLHOUND! We SEE you! Don't think you can get away with anything!' sound.
My friends also visit with a doxy who chases them and pulls out feathers but has failed to do real damage (he now gets tied up if he goes out since he can dig under our fences which were designed for much bigger dogs) They make wary sounds and keep an eye on him too. Any new dog that shows up is treated as a potential threat. Loki's the only one they trust. Smart little featherbrains!
