I have to "x3" Stacykins...I hope I didn't mislead you that a goat can be by itself with chickens as a replacement herd. We had the one for the sole purpose of being part of a herd, but they had to be QT'd first, so in the interim he was alone with the chickens. But they definitely need companions, which is why wethers are so common in small herds; example - one buck in a dairy herd...usually not kept with the doe due to breeding schedule, so he and the wethers are a buck-group seperate from the ladies...No breed of goat is better off alone. So no, pygmies are not better of being kept with chickens and no herd animal companion.
