Is this goat agression?

Hello! I am a new owner of a 5 year old Lamancha wether that came with the house we bought 6 months ago. He is usually a sweetie and has come to really love and trust us as we give him goodies, lots of love and brushing that itchy goat hide. This morning his door became jammed and I went into his stall to open it and let him out. He repeatedly jumped up on me (and he is Huge) all the while licking his lips like crazy. I yelled at him to get down and pushed him off getting out of that stall as quickly as possible. Can anyone fill me in on why he got this way or what I could do in the future? Thanks so much!

 

I wondered why the old owner had only him. I remember hearing that he was too aggressive with another goat they tried to bring in so the did not keep it. He is fond of and protective of the chickens that share his pasture. Oddly enough I moved the younger chickens in the stall next to his to the big coop just last night. Maybe he is lonely. There are better ways to ask for my attention.

 

Thanks! It sounds like this may be the case if I did get another. The old owner did not say anything, but his son in law was by picking stuff up and said the tried to get him a friend but it did not go well. Peppy the goat also ate the tail off of a pony they put in with him to sleep one cold night. The pony's owner never forgave him, lol.

 

He is great with the chickens. He is a fantastic watch goat. They free range together all day so it is just the sleeping quarters that got moved. The chickens are smart enough to stick with him in their large fence pasture and I have not lost one yet to hawks yet my neighbors lost all theirs. Hopefully he will adjust to the new sleeping quarters for his feathered friends.

 

He is a lamancha...no ears so that would be hard The squirt bottle seems to be a good deterrent to jumping at least.
