People new to goats are often surprised at how depressed a goat can get from their transition to a new home and how hard it is to gets goats to accept each other from different herds. We purchased two goats a year 4 months ago, adult does, and my herd of almost 20 adult does, wont have anything to do with either one, the beat on them constantly, and I have to pen them separate at night so they can have a chance to eat and even stay under shelter. Yes, a year and 4 months. Now most of my herd has been here their entire life, including several 7 to 9 year old does, plus their grown offspring. They are a well established herd, it is a pain to introduce new animals.
Good luck with yours, You just have to see how it goes and make adjustment to how you feed them and house them so each goat can get shelter and feed.
