We have a 2 year old neutered bunny named coyote, who lives in a hutch and run outdoors. He is played with less in the winter, so we think he would benefit from having a friend. Which brings me to the question: Does anyone have actual experience keeping an intact doe and a neutered buck?
As Bunnylady has pointed out, two rabbits can get along just fine until they don't. Then it can get pretty bloody. Females are often very territorial. Odds are she won't be happy with an intruder. Your male can get along just fine without a companion.
