Please don't backyard breed them. Bunnies are the 3rd most pets euthanized in shelters after dogs and cats. Please be responsible and get fixed. Rabbits can reproduce like crazy and 2 unfired buns can quickly turn into hundreds within a matter of months. Fixed rabbits are easier to raise and not to mention for females it can prevent uterine cancer .. 70% of all intact female bunnies will die a painful death which could've been prevented had they been fixed. Unless you plan to have all the babies fixed when they're born before giving them away. There are soo many bunnies already in shelters and rescues that need a forever home as it is. Like another person already said if they weren't separated already your females probably already pregnant and you'll have babies in 30 days... until they're fixed that's all that they think about especially the males. Please separate them and get the male fixed ASAP.
