D24 grows everytime I see him/her and this morning D25 had a little flight out of the nest cup. Mom got up and D25 was attached as she did her little fly up and hop she dropped D25 just outside of the nest cup. It did not take her long to open the gate to the nest cup, scoop the little darling back in and close the gate. Close call, but as they say this nest is a no worry zone, the parents know what they are doing.
