As we continue to look for goats to start our herd, I am seeing a few adds for goats that are a couple of years old and have never kidded. Is there a window to start breeding them that closes if they become too old? I Breed rabbits and haven't breed a rabbit for the first time that was over two years old because I have heard that it is more difficult for the doe to pass babies if she starts breeding late. Just wondering if the same is true for Nigerians, and if 2 years is too late.
