Thanks everyone. I think I should be able to remove top level ok. Still chirping away but not been sighted yet. Pip is doing ok I think...spending plenty time with them but going stir crazy without her wheel! Goodness knows what she will do without top level!
Can still hear them chirping away but haven't seen them yet.....so not sure how many there are. Can anyone tell us when they will start to emerge from nest as we are dying to see them??
