LOL, you are right, it took me a while to learn to not run when a goat lowered his head and came running, then I learned that if you just stand there, he will rub his scent on you.
Except for one mean old billy, that I had to take to get the ladies of the herd, and he did not like me and had the full intent to stomp me, no games with him.
One family that I knew, would buy goats, kill them and then cut gashes in the legs and fill them with the water hose, so the skin did not touch the meat.
They do have glands on the side, some where I read they have 7 scent glands.
If you have goats, watch the does, they will rub their heads and sides on you.
Gall, yes that is the gland I was thinking of and could not recall the name of, it is one of those things that I learned as a child, for we did not have refrigeration, so killed and cooked it the same day.
Yes, today they do chill them as soon as possible.
Thank you for sharing your knowledge, for it is the little details that mean so much, if we are all suddenly killing our own foods again.
Mary taught me to pull the chickens neck hard and then they do not flop around, while you chop off the head.
