You don't know what it was. You don't know if it's legal to kill it, or the circumstaces under which you may protect your livestock here. You don't know anything about this place.
It seems to me you have nothing constructive to add to the conversation.
Yeah, and apparently you don't know what it was either. Also, you said it was illegal yourself

Also, you had a pretty strong opinion on how I was not a responsible chicken owner and I "cared to much about cost." Well I have an opinion about you, you are irresponsible because you let your birds free range in a national park, you are pretty much feeding the wildlife. Very irresponsible, if you get chickens how about you protect them from predators?
A national park seems like a horrible place to raise chickens in the first place, I know you talked about how horrible they were treated before and how you saved them but I think the best option would have been to stop raising them in an area full of predators that you can't legally kill.
The notion that keeping chickens outside in an area full of predators that you can't protect them from is acceptable or even a better option than keeping them in a run is in my view false and harmful to chicken welfare in the long run.
