Last year we had sea gulls nesting in the gaps between the chimney pots. One chick fell down and we tried to save it but it died a second fell down the chimney and had to get a gas fitter in to remove the fire to get it out. This one went to the RSPCA, our German Shepherd looked puzzled having it in the house. So this cost us having the chimney swept, caps on pots, fire serviced and the 40 year old central heating boiler that hadn't been serviced for 30 years condemned and a new one fitted. All in all quite pricey. And they are back this year :headbang:
