The egg that never was :(

I know you're not supposed to go in to a box until October, when nesting season is over. But the nest box was rotten and hanging on by a thread. We had been keeping an eye on the blue tits and we hadn't seen them in a long time, so we decided to take it down. There was a lonely dead chick and a perfect egg, smaller than a mini egg in fact and the nest was perfect and full of our dog's hair!

So there you have it, something positive came out of something sad, because i'd never seen a blue tit next before.
