Had a really strange yb drop with mine last night, would'nt come in, thought i was seeing thing's with the sun, but was deffo 100% what i saw, It was a normal chq w/f down 1 side, and the other wing was a bronze chq. I had to look at this bird 2 or 3 times before i believed it. Was a cracker aswell, Anyone ever seen a bird like this before? or indeed got 1? He stayed for about 5 mins after mine went in, Then went. What causes this? Any ideas or theories? And no i dont need specsavers :-) It was before i had the vodka :-)
