Steve’s nest boxes

Thanks all, good news is, they fledged early this morning. So another three join the Blue Tit population! We’ll miss them though.
I am designing new boxes for next year, and will look for different camera options I think.
Our cameras have been pretty good but, room for improvement.
Sammi, sorry I forgot to reply, how are yours doing?

How long should I wait before cleaning out the boxes?
