    Five weeks. However, that’s similar to a 14 yr old girl getting knocked up, so I wouldn’t support such an idea. This is the time when you either need to sell or separate your hamsters.

    3 weeks

    young hamsters become sexually mature at 4-5 weeks. they will start to breed at this age. but you should not breed them at this age because they are still too young to have babies. the ideal time to breed them is about 3-4 months.

    Unlike the Syrians, dwarf hamsters are sociable and can exist peacefully both in the wild and in captivity. They do well when paired up young and allowed to mature together.
    Although some dwarfs may be sexually mature at 30 days, the Campbells, Siberians and Chinese hamsters will normally begin breeding when they are between 60 and 90 days old. Roborovskis are not as predictable, they have been known to produce their first litters from anywhere between 4 to 18 months of age.

    The gestation period for dwarfs runs between 18 and 30 days, with 21 days being the average for all dwarfs besides the Roborovski which is normally about 30 days long. With all dwarfs, there is always the possibility that the pair will mate again within a period as short as 24 hours after giving birth to a litter. Other pairs have been known not to mate again until the litter is weaned.
    Just prior to giving birth, the female Siberian, Chinese dwarf and Roborovski will chase the male from the nest for a few days of bachelorhood. It isn’t very long however before he becomes a valuable contributor in assisting with the little ones.

    The Campbells male, however, interacts from the time of birth and doesn’t get these few days of rest and relaxation before being called upon to help with the young. According to a study conducted in 1998 by Katherin Wynne-Edwards at Queen’s University in Kingston, Ontario, “Djungarian (Campbells) hamsters are paws-on dads.”. Canadian scientists have observed the Campbells males helping tp pull babies from the birth canal of the mother, lick off birth membranes, open the pup’s airways and then “share a snack of afterbirth with the mother”. The report also states, “Djungarian fathers have hormonal fluctuations similar to the mother’s around the time of birth. Estrogen and cortisol levels rise before the birth, and then fall away afterwards as testosterone levels rise. This does not happen in the closely related Siberian hamster.”
    Although most dwarfs are from the same geographic area, Campbells dwarfs are found in a harsher desert environment. As a result, it is believed that males remain in the burrow at the time of birth to help keep the female and young warm enough to survive. “We have hypothesized that becaue of the early hormonal changes, Djungarians would show the full range of paternal behavior,” says Wynn-Edwards. “They did. Not only were they exemplary midwives,” she added, “we saw the mother and father both holding the afterbirth with four little paws, sharing it fifty-fifty”.

    Hi :)

    How old are your babies? (ok saw another post, they’re 17 days old as of today)

    What type of hamsters are they? (They’re dwarfs, but what species of dwarf?)

    I can tell you already that they’re too young to be mating, but not too young for them to be play fighting or dominance fighting.

    You DO however need to find a separate cage for the male in the next week or so.

    Robos will generally mate starting the first spring after they reach sexual maturity (which in nature would mean next year – but indoor conditions are different) – so if they’re robos you *could* be safe for a little while – but they still need to be separated.

    You’ll also need to worry about the boy mating with the mother if he reaches maturity and is still in the same cage. If it’s a campbells or winter white, they’ll reach maturity and generally start breeding like bunnies at 4-5 weeks of age. I’m not so sure about chinese dwarfs as they’ve been illegal in both states where I’ve done rescue.

    If you can answer those questions for me – I can give you specific answers! I don’t want to generalize or overwhelm you with information not specific to your particular animals :)

    I’ll watchlist your question for updates, or feel free to message me directly :)
