I have 3 goats at the moment all female. Two are called the "twins". They are inseperable and look identical except for their horns. One recently had a baby and I sold him the other day so she is rather upset. Her "sister" on the other hand has become, to put it bluntly, a *****! She used to be alright with being pet and would every so often rub her head as if playing but we always discouraged this. With in the past 2 weeks she has become very aggressive. She was starting to become more pushy and try to butt me but I always grabbed her told her no and shoved her away. I had a family come to pick up some chickens. I brought them into our barn pasture but didn't warn them or anything because all of our animals are friendly, we do not tolerate aggressive behavior. They had a little girl around 6 who was standing there looking at one of the other goats and Venus (the trouble goat) walked over causually and smacked her with her horns! She didn't hurt her but the little girl was shooken up and upset. After that was resolved she kept following us everywhere trying to do it again to someone else! I kept shooing her away, grabbing her and shoving her the other way but she would not leave. A few days pass and another family came to get a baby goat. This time I warned them about her and I was there to block her away from their young daughter. Same thing! She kept coming over like she was going to be friendly like the others and be pet but I could see "the look" in her eye of her wanting to hit someone. Another few days pass and another family came to get chickens. I warned them about her and told them to shoo her away. While I was chasing an escaped chicken I caught her and was bent over and she ran up behind me and rammed me! I was so surprised I dropped the chicken and had to take a minute to realize she head butted me! None of our goats have EVER done this not even the bucks we have had. She just will not stop! Today I was cleaning a stall with my brother and of course there she comes walking over with her sister to "greet" me. She hasn't hurt anyone but I for one have grown sick of her nasty behavior. The whole time I was down there she was testing me by going into the stall behind my back and going where she knows she should not be. I accepted her challenge and would put her in her place every time she got that "look" or kept testing me. I would grab her by her horns and hold her or shove her or put her head to the ground and she always came back asking for more. I am at a loss. None of our other goats have behaved this way and the few times they have they learn I do not tolerate it. I don't know why she has become such an aggressive wanna be dominent goat all of a sudden. One of my guesses is she is upset she was the only one with out a baby? We suspect she is pregnant because her milk dropped a little while ago. This would be her first baby so I know it would be a month more before she would give birth. Could the pregnancy make her overly aggressive? If you can't think what is causing it what is another way I can disapline her? Also she is not the dominant goat in our flock and our dominant one has an iron fist when it comes to bossing the other two around.
The trouble maker is on the far left.... her sister is on the right and her baby in the middle.
