I think introducing your dog to the chicks is highly dependent on whether your dog knows YOU are the Alpha to your pack.
I'm proud to say my dogs have not killed or harmed my chicks, but that's because I am making the extra effort to start introductions now, while the chicks are still young. Just like when I had each of my children, I let the dogs get familiar with the scent first. I did that for the first two weeks--and still am, but now they can see them from a distance too--and gave the dogs extra attention. The key is to let them know you are ADDING to the family/pack/flock and that they (the dogs) are still VERY important to the function of it.
Just like the pecking order, dogs need to know what their place is in the family/pack/flock. If the dogs feel like the chickens are taking their place, their first instinct will be to "meet the challenge"...doggie style! Unfortunately, right off the bat, they know they will win...and the chickens WILL lose. So you have to start slowly, for the sake of everyone.
Right now, the chicks are housed in an area
behind the dogs' kennels. The dogs can hear & smell them, but can only see them from a distance when I (or another family member) am around.
Eventually, the plan will be to take the dogs for a run (or long walk) to expend most of her energies, then do a face-to-face (individually works best if you have more than one dog). Allowing the dogs to run/walk off most of their energies before the introductions will put them into a mellow mindset to greet the chicks. Next, I will introduce my calmest dog, Maui Lani, FIRST because she will be an "example" to Honey (our other dog)--I will let Honey observe from a distance. I WILL BE CALM. I WILL BE CONFIDENT. If I show any sign of anxiety my dog will pick up on it & react...badly. I will bring her--not the chicks to her, not her to the chicks hutch (that would be a HUGE and disastrous mistake)--to a place where everyone normally shares time together. I will have her lay down because this is a submissive position for her. This is neutral territory to her...not HER space, not the CHICKS space...EVERYONE'S space and she knows it.
At this point, I will
nonchalantly bring the chicks in a cage--always watching my dog's reaction--or have someone else do so. The last thing I need is to be alone, carrying the panicking, flapping chicks and trying to play keep away with my dog!
As long as I remain calm and confident, the introductions should go smoothly. ***Oh! If you should sense some anxiety in your dog at ANY time, FIX YOURSELF FIRST before you abandon the introductions. More than likely, your shoulders have tensed up & your dog is picking up on it. Loosen up, head up...show calm confidence. She'll get back to that state of calm as soon as you are.
**Picture the calm state: Your dog is laying down with her head up, tongue hanging out, taking in the sights and sounds with a "I'm so happy, but tired" look on her face, and tail lazily wagging. GOOD SIGN!!
**Now, picture the alert/anxiety state: Your dog's ears perk up, eyes fixed on its target, her head is low (or she bobs it up and down trying to get a better scent/sight of her target), hair on her haunches standing up...more than likely, she's standing or sitting up at this point. BAD SIGN!!
Once the introduction of Maui Lani is done, I'll repeat the process with Honey. Since Honey is more active, I usually take her for a bike-run first. She's usually too tired to care what happens when she's done with that! LOL
I plan on repeating this process for the week or two, a few minutes each day, until the girls and chicks have accepted each other. I know my dogs, if they accepted my "just as nuts as starving monkey's in a banana patch" kids, they'll be just fine.
A good thing to note is how well you know your dog(s). I couldn't possibly do this with my neighbor's dog..he can barely poop in his own yard, let alone THIS! LOL
Good luck with introductions & I hope this helps. I've owned dogs since I was old enough to crawl out the front door and unlatch the kennel doors, so my experience with them spans more than 30 years. Although I'm a first time chickie momma, I'm an "old hand" at dogs. I'm Alpha, hear me bark "woof bok woof bok bok!"
