Its not uncommon for moulting to occur on a poorer quality food. The body uses nutrition for the core body functions first, ie heart beat, brain, muscles etc and often the nutrition has been almost depleted before it gets to the skin and coat, which are essentially made from protein. They also shed fur as a way to eliminate "toxins" from the body.
We do see this "detox" process with a fair number of dogs switching to Eden (or other high quality foods) and it can take up to 3 months for the body to fully heal itself.
Also remember that a lot of dogs are currently shedding/blowing their winter coats, (been ongoing for several weeks now across the online forums) and Huskies will shed enough hair to make a new dog.
stick with it, and try a furminator to help brush the excess loose hairs away, many husky owners swear by them.
