Would seem to me a waste of good meat to let the bird rot. As far as killing it, without a gun you have to resort to sticks, stones and axes. Just removing the toes and wings seems insufficient but skinning it is a good start. Also, would not hurt to gut it before freezing. As far as taste, pea fowl taste a lot like phesant or guinnea. A bit dry if you are not careful cooking them but good dark meat and flakey white.
Can't imagine this guy going to jail over this.
I think the fact that the bird
belonged to someone is enough to at least fine the guy. After all, these are not wild, native birds, they are exotic and are connected to people through ownership.
I had a weasel after my birds two nights ago, and believe me, you don't want to know what I would do to that weasel, be it four-legged or two-legged!
