Thanks so much, guys!
I've definitely read up on goat aggression and it turns out my tiny guys are doing a few things I need to talk to my boyfriend about so we can nip it in the bud, so I really appreciate you steering me in the right direction! I was never raised around farms and had about 10-12 dogs in my childhood home over the years, so I'm working on learning the differences in goat and dog behavior.
Most of what they are doing (they're crowding the gate when I arrive, and jumping on and crowding me when I have food for them) wouldn't phase me with a happy lovey dog, but I'm really glad to know this is bad social form and something I need to work on for my goats. I've been pushing on their chests (never their heads!) when they jump on me and only feeding them treats when they are on all fours, I'll have to figure out a way to keep them from crowding the gate now... I've reviewed some videos about how to train goats to back away from you on cue, wish me luck!
Once again, I really appreciate all you guys' help! You guys are great!
