How many do you have? I have 3 one big one that my Grandpa made me and a nest packet one that I got a botanic garden and a lil wooden one that I got in a £1 shop Im not to fond on the pocket one because Ive noticed a few bird trying to pull the brown things out but then again Im sure the birds would love them. Lots of birds have been going up to them sencing them out so fingers crossed :eat:
