Hi. Pedigree Rice and Chicken contains Poultry Meal and Meat and Bone Meal so if your Husky is intolerant of anything but Chicken, this food will be aggravating her. It may be that she is intolerant of some of the other ingredients though such as Corn and Corn Gluten. If this is the case, then you could try any of the foods you have mentioned, although I would suggest that you try a fish based one first as this seems to settle many dogs with poor digestion. Some of the foods are suitable for puppies and adult dogs - I know Eden is and I am sure others are, but as you have two such different breeds, you will have to manage amounts and exercise carefully.
Another food that may well suit both is Gentle Cold Pressed - it contains Chicken, Duck and Herring as the meat sources and although it contains Brown Rice I have seen many dogs do really well on it. Even tiny dogs seem to manage the Kibble (which is pellet like - almost like a pony nut). I have had chihuahua's happily eating it in the shop, much to their owners suprise, having had them on small bite kibble previously. You only feed 1% of body weight (I think this might be the same with Eden, MWH and others you mention too) so it is easier for sensitive digestive systems to manage and can be wet down easily for a puppy or a sick dog.
If you do want to try a food that is solely chicken based, Barking Heads Tender Loving Care, Simpsons Sensitive Chicken and Potato and Laughing Dog Baked Chicken Grain free are good options but are not all Life Stage and only between 45% - 60% chicken. An 80/20 that I know is single protein Chicken is the Aatu Chicken. It is the most expensive but may be a good place to start if you are sure that her intolerances are meat based, although it is not all life stage as far as I know.
Hope this helps - all the companies you mention are very helpful, so you could ring them and they will talk you through your options.
