chicks hatched

I have set up a nest box with camera at the school I work at and this year as last, Great Tits have nested but this year they are a full week ahead of last year with 4 out of the 9 eggs hatching today. In fact this has been the earlest nest in this box for the past 5years with Blue Tits in before.

Is this unusual or normal for this year?
