A phrase is a collection of words which holds a concept ad can be used as a unit in a sentence.
The phrase that should be revised for a more parallel sentence is "keep out of cold" because if others are blocked out, it wouldn't make a proper sentence as it would look something like, "pet canaries need keep out of cold".
Properly revising it would look like, "pet canaries need to be kept out of the cold"
