Great Tit

Great Tit

Observation - Great Tit - UK and Ireland. Description: I have a pair of Great Tits nesting in a terracotta jug with a long narrow neck. They hatched around 14/6/11. Will I need to turn the jug on its side to allow the fledglings out after 18 days, or are they best left well alone?
