I thought about keeping a few ybs off my 2 pair birds flying out so have made a new small shed.
However had a change of heart as we now fully intend moving this year, hopefully somewhere pigeon friendly as its a waste of time here so pointless putting it up now.
Its all brand new timber clad in new marine ply - 4 coats dark wood preservative and roof felted with the heavy green mineral felt. Slidng door on side and perspex and dowel sputnik type trap on front window. All sectional you can put it up in 20 minutes, easier than an Ikea wardrobe! Its just @4 ft square, big enough for a few fantails, tumblers or single flight breeding for racers or even dog kennel.
Its even on wheels so if anyone fancies it cheap or for the kids/grandkids I'll let it go cheaper than a rabbit hutch.
