Thanks all for your help! The hunt is in WA state.
Interesting comment about the young billies, JP 100. I wondered the same thing while we were looking at them.
Any tips you guys have on making sure I shoot the right goat once the season opens? All three billies are hanging in the same general area. Will longer hair make ID'ing the right goat more difficult? And the emergence of glands?
My plan now is to bring photos of the big one with me on the hunt and compare it to whatever goat we're observing. And watch them for a really, really long time before pulling the trigger.
Any other tips or distinctive stuff to look for would be appreciated. I'll make a post after the hunt to let you all know how it turns out.
The above photos are good, look at the head/neck and 'stance' of the animals. that applies to pretty much all species. Young animals have baby faces, that 3rd goat is a good example. His horns look quite thick, but thats because they are short, and his face is small. compare that to the big nanny above and she is a whole different animal.
Dont pay much attention to glands, all goats have em.
A mature bill will walk with a swagger, he will be well built and look solid right through his body. A good billy will look like a white shetland pony haha.
Study the body/behavior long before you look at the horns.
