I have a bee colony that have set up home in my old chicken shed. We were going to pull it down and dispose of it this year but i've noticed bees going in and out of a small hole in the side! and sure enough they've made their home there.
Now they don't bother me and i don't bother them, they do buzz around whilst i hang the washing out which is close to the shed, but we are rubbing along nicely at the mo.
Do i need to do anything for them though? I have a wildlife friendly garden ( WEEDS)

but i'm happy for them to stay there, I just wondered if it's ok to leave them there
