<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fledgling's home</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for nest that I've seen before include "breeding-ground" , "Structure built by birds" , "In which to lay eggs or give birth" , "Sent to avian home" , "Rook's residence?" .)
