If the rabbits have lived together before he was desexed, then as soon as his stitches have healed they can be housed together again.
If you are introducing the two bunnies for the first time, then wait until his stitches have healed before letting them meet each other in a neutral territory like a bathroom. If they fight, separate them. You might need to introduce them multiple times before they stop fighting and then you can try housing them together.
Some breeds can be sexed by color or by wing feathers (auto sexing). Otherwise, you will need to wait until they are older to sex them.
Female rabbits normally do, if you're putting two female rabbits together it's best if you get two sisters. It's hard to tell until you put them together really, but it's best to put them together while they're still young.
It will take around a month until the babies are born. You'll need to separate the female rabbits before she gives birth and until the babies have grown up. You should be able to put them back together after. But the rabbit without babies may get jealous and kill the babies.
Mini lop rabbits have the same genitalia as other pet rabbits. The only way to know for sure if a rabbit is male or female is to examine the genitalia. See the related question below for details.
Rabbits sometimes just don't get along, even when they've been neutered/de-sexed. Before you let rabbits live together, you should bond them: until then, they should be separated much of the time (and always when you aren't there to supervise). Bonding can take anywhere from two weeks, to many months of patience and hard work. Never let rabbits fight, and biting counts as fighting! Fighting can be emotionally and physically traumatic and can lead to serious injury. Rabbits are more likely to fight if they're under stress for other reasons, too. You should minimise stress in your bunnies' lives. See the related questions below for more details and helpful links.
Rabbits become fertile as young as 4 months of age. If you are intentionally breeding your rabbit then you really should wait until she is at least One Year old.
To breed rabbits, put an unnuetered male and an unspayed female rabbit in a pen or some open area. Keep them together for a few hours until they mate. (Do this at dusk or dawn. That's when they are most active.)Wait 28-31 days until the rabbit gives birth.
They can be vent-sexed by very careful manipulation of the vent, but it is something that requires practice and is not simple to do. Most people who breed ornamental waterfowl have mastered the technique.
You can't just tell, you have to sex your ducks. The best thing you can do is take your ducks to an avian vet to have them sexed or just wait until they are old enough to breed which is about six months old, and see if the eggs hatch.
actually , female rabbits should only have babies whil it is under 1 year old,because if a female gives birth to a litter of rabbits after it is one year old then its pelvis will be damaged. but this is not necesseraly always true .also if you want to check about female rabbits having babies after its 1 then go to petsplanet.com and go to breeding section on rabbits :)Actully rabbits shouldn't be breed until 6 months or later for larger breeds and can safely continue to have litters until 2 or 3 years og age and maybe later. Bucks can breed from about 4 months on but may not be effective once they get old.Answer:A lot!A rabbits gestation period is 30 days and they are able to get pregnant again immediately after having the previous litter of kits. Rabbits also have a horned womb, which means they have two spaces in their womb in which they can hold two separate litters. They can range from 1 kit to about 15.rabbits are induced ovulators, so as soon as there is the prescence of a fertile male around they produce an egg.A female rabbit can start breeding by 4 months old, a male by 3 months.It is always reccomended to get your rabbits fixed as female rabbits have an 80% chance of developing some form of reproductive cancer by age 4.Also, there are thousands of rabbits in shelters and rescues that need homes. For each kit that is bred that's one less home to a bunny in a rescue.
A butterfly Koi is simply a Koi with longer and straggly finnage. They are sexed in exactly the same way as all other Koi and/or goldfish. The Koi does not reach sexual maturity until it is about 10 inches long so it can not be sexed until then. Once sexually mature the females tend to have a chubbier appearance than the males and (as with goldfish) the males develop whitish spots (Pimples) on their gill plates and pectoral fins when they come into breeding condition.
Baby rabbits (called "leverets") are cared for by their mother until they are able to get by on their own.
