What does this mean?  Tied together with what?  String?

Perhaps someone can explain what is the shayla here.  I thought it was
black letter law that "kol yeter kenatul dami", and therefore this
chicken should be clearly treif.  What is the sevara to rule it kosher,
and what has it got to do with the legs being "tied together", whatever
that is supposed to mean?

BTW, this is far from unheard-of.  At this URL you can see a picture of
a (dead) four-legged chicken that was brought in to the Crown Heights
