Yes. And some, like crows, have entire family structures. If something happens to the offspring in a group, someone else in the family takes over. So its possible they are cheating, but only within a limited genetic 'family pool', which makes sense from a social structure standpoint. Actually, crows are bloody intelligent, check this out. I promise it is not a waste of 9 minutes:
