I have a pair of great tit's (I believe) frantically feeding chicks in my bird box. Can anyone tell me, I'm assuming they lay 8-10 eggs if they all hatched what is the average rate of survival to fledge with them having good food source available etc? Thanks.
I've posted the best picture I was able to get at the mo as they're so quick but will work on better ones.
