I said I'd come back and post the answer to my mysteries. Turns out they were crap mysteries, so I shouldn't bother really. I pretty well mucked the whole thing up right from the start. I forgot to save the originals of the rooster's rear end and the old truck. Have just been for a walk to get another shot of the old truck but am not keen on going to find the lovely rooster as it is unlikely he will be so co-operative twice, but that's him at the front of the flock photo below.
And now....now I discover I didn't even link my Friday's post to our group website. Why not check it out to see what the much brighter sparks than me came up with.
