Hey there! Thanks for popping up on the forum. I saw that you had posted and forgot to come back and comment on this.
With the comment to disbud the goats, it is up to you as a farmer but we don't suggest people do it because it is such a unique part of the goats. Again, we do realize this may not be realistic for every person so it is up to you!
With your goats being turds... I know with our goats they tend to go back to their feral roots when there is food around so they will push other goats aside, really beat them up and run them off. With all the goats we have, we have found it is easier to just let them kinda beat each other up because the other goats, over time, will learn to back off during feeding time and then go eat afterward. It looks nasty watching them fight but I truly think this goes back to their feral instincts.
I have found that the Arapawa have very strong family bonds, so keeping mom and babies together, they will pretty much always stay together unless you separate the baby for a few months after weaning. This kinda helps get over the "family" mentality, but again it's those feral instincts! It sucks having the other goats beat on and I hate watching it, sometimes being able to put things for the other goats to climb on and get out of the way helps. They will get them in the corner and just go at them. Over time they will stop after they get used to each other but it can take weeks to months to do this.
I hope Marigold is doing okay for you! She has always been lower on the totem pole so I don't think it would take long for her to back down and just stay out of your other does way.
