I am so happy as this morning three of my blue-tit chicks left the box and we saw them go,my two children were amazed.I had no idea how many were inside or if we missed any leave but to watch three safely fly off was great and very rewarding.Still have parents feeding the chicks in another box but they to must be almost ready to go,i will miss the comings and goings of the parents and the cheeping from the chicks!
