Hi my sister has been gardening today and has just found 3 baby what looks like blackbirds inside her green bin with lid closed had a pot and other things on top so no way mum can get in for weeks!! The babies aren't making noise but are alive what should she do please? Ive tried calling local rspca and rspb both say closed! She isnt sure what to do? Its very hot so i said she should move big green bin into shade and trying finding worms for them? But its maybe the heat thats kept them alive so long?? Does anyone know who we can contact please near Beaconsfield?
