Swallows but no Amazons

For the past couple of months going in and out of the potting shed has been something of a competitive sport. The swallows arrived back from Africa a couple of months ago. Most of them nest in the un-used barn behind the house, but this year a pair decided to build a nest in the rafters of the potting shed.
It had a certain rustic appearance from underneath, and for a long time we presumed they were a pair of first time breeding birds who were getting the hang of nest building, and probably wouldn't raise a clutch of eggs this year. Apparently this isn't unusual with swallows, building your home using beakfuls of mud isn't an instantly acquired skill!
A couple of days ago though space must have got a bit cramped because 5 babies appeared out of the nest and sat on the rafters building up their nerve to make their maiden flight. 
They're still coming back and roosting in the potting shed, and are making sure we know about it, for small birds the quantity of poo is enormous!

Every now and again they need a little help with their exit strategy... after all a window and a door look much alike in swallow world. They also still have their lovely cute baby mouths, the white rim helps the parents to find their beaks and stuff in insects. 

They're also much paler than the grown adults. This is one I had to rescue from my house a couple of years ago.
