Huskies and Malamutes have extremely high prey drives and are independent thinkers - they are not in it to please you. They can sometimes be kept with cats if raised with them but smaller animals and birds are viewed as prey. Anything fleeing is prey, no matter how big. They are hugely intelligent and need to work and run.
Our neighbours had two Malamutes. One was obsessed with cats and would kill them. She had to be put down. A pair of Huskies were getting out locally and killing sheep.
It will take a lot of training (do it individually so they cannot feed off each other) and be prepared for the fact that your dog's personalities may make it impossible for them to be trusted with your chickens. I've read of German shepherds on here who are as good as gold while their owners are around, but as soon as no one is looking they'll grab a bird. Not all dogs can be trusted with livestock, even with all the training in the world.
