I am super new to goats. We bought a Nubian doe in milk with her 2 4 month-old nursing doelings. A friend on a nearby ranch asked if we could care for her pregnant mini-Nubian. (She has a swollen shoulder joint and needs a break from the miles of mountain roaming with her herd.) Apparently Lucy (the Nubian) and Oreo (the mini-Nubian) were both queens. Oreo is horned, Lucy is not. And Oreo is now the queen. She is merciless to Lucy. She chases her and belly/udder butts her. I know that some aggression is normal for establishing the new hierarchy, but Lucy gets no break. Oreo is pretty good with the doelings (ignoring them most of the time.) So how much aggression should be tolerated? Is it going to get worse before it gets better? Or should I just find a new home for Oreo?
