I have a mini rex doe that just turned 6 months. When I was checking on her I noticed that she was acting ready to breed so I flipped her and she is a dark red and purple down there. She is 3 pounds 7 ounces. The bucks I have are 4 pounds 5 ounces that is 2 years old, 3 pounds 10 ounces that is 6 months and then the other I havent been able to weigh but is around 3 and a half pounds and is 6 months. Do you think she is big enough to breed? And if she is which buck do you think would be the best to breed her too?
