I saw these pics the other day somewhere else.

Not unethical or cruel, a fact of life of being a hunter.

As Ben said, it happens if you shoot females of any animal. Be it Fallow, Roo's, Buffalos, Pigs, Foxes etc and they are just the one's I can think of that I have been involved with.

Now in regards to posting the picture in a public forum or on Facebook, not such a good idea IMHO.
