This has been going on for the last couple of days - head butting, biting, ramming each other - gracioius!! If I didn't know better I would think the three of them are PMSing!! Every once in a while, you will have one that get ornery but not all three!! The buck is smart, he stays out of their way!
It could be that the three of them are fighting over who is going to be "alpha" or "head" goat. Right now Elissa is. So Carly and Maribell might be challenging her and also fighting over who is going to be "second in command." I am going to do like the buck is and let them figure it out!
