I had a magpie when I was a kid who just lived in the garden, he had a duff wing due to a bit of poor shooting but used to get about, a bit like a hen he could flap up a few feet but that was all, had him (or her) for about two years fed it on a mixture of worms and dog food, he just hung about for the grub and became tame enough to sit on your hand and be fed
wasn't a bad life for a cripple but still found him stiff as a board one morning, I still get a twinge everytime I shoot one
