Yes, great advice above...definately learn how to ''read'' your dogs body language and thoughts- the idea is to be a stern 'pack leader' -scold your dog for the mere THOUGHT of pouncing a bird...if he gets away with pounching/chasing he is apt to remember the FUN of it rather than the consequence of it which means he may very well attmept it again and again. Learn to correct before its allowed to reract. Hopefully he does not have a high prey drive as its hard to train that out.
Definately raise the chicks visibly to the dog/ meaning indoors or in easy view of the dog, care for them like little family members, dogs usually realize when something is ''part of the pack''. Handle the chicks around the dog, allowing to sniff and nothing more do this every time u care for the chicks. I call all tiny things ''babies'' around my dogs and they are trained to be very calm and nice to ''babies''...so anytime i want them to treat something with care I say "its a baby" and they pretty much know what that means. My cats were raised the same way. They wouldnt dare kill a baby chick.
I have 5 dogs, a pitbull, a smooth border collie, an aussie/pit, an aussie/sheltie, and a jackrussell/beagle/border collie mix. And they ALL get along fine with the chickens. in fact, the chickens rule the dogs -chicks hop all over them. The dogs however follow the chickens around as if they were ''candy dispensers''. lol and they often sneak in the coop to eat chicken grain. (which gives them explosive diarreah so I dont know why they insist on doing it!) I never worry about them with chickens...though the pitbull loves stealing eggs. lol I collected some one day and placed them on the deck....next thing I know they are gone and the darn dog's got yolk on her face! lol
Good luck with intergrading dogs and chickens! Worse case sinerio the chickens will need to be securely fenced.
Growing up, we had a family dog (rotti/pit/beagle) she would kill and EAT squirrels, rodents, ground hogs, and chase strange cats/dogs out of the yard...but she NEVER touched our pet rabbits and our chickens. We never even trained her that way, some dogs have good pack insticts and can tell what is supposed to be there and what is not.
I didn't placethe chick there, it fluttered up on the og's head and I just held them still to take the pic. So cute! lol
