Well things are really hotting up now. The three chicks are very active and food is in constant supply by Wills and Kate. Kate has been encouraging the chicks towards the nest box hole by holding food in her beak and not letting go of it and they've been looking out of the hole a few times today.
The chicks have been doing a lot of preening, wing stretching and fluttering and so I reckon that they are ready to go. It could be today although it's a bit late now, but it will probably be early tomorrow, so watch this space.
