In stanza three the speaker says "Where did we learn to be unkind", referring to him and his brothers.  The first thing that comes to mind is that these boys learned this from their parents.  It also reinforces my point that the boys are up to no good while they are locked out of the house.  Whether it is actually stealing a bird's eggs or other forms of mischief, it seems as though their parents behavior is the reason they are doing this.
