Chinese Breeders help!

[Hana]

Heya,
I’ve got a friends two Chinese hamsters for a couple of weeks (I’ve had them since Tuesday) and have been trying to breed them with my female Chinese Cracker.
I’ve only got experience with Syrians but from some reading found that it wasn’t much different, but don’t know how true this is?
So what I’ve been doing is putting one of the males and the female in a storage box and wearing thick gloves watching them to make sure there is no fighting. I didn’t want to put her in the male’s cage as some sources told me to, as there are two males and I thought they might start fighting, also she seems to have a preference in the boys.
Does this sound like the right thing to be doing? How else could I do it?
She doesn’t seem to be ‘standing’ with her tail in the air like the Syrians do though, so this means she isn’t coming into season?
I read that this could be because she isn’t getting enough hours of daylight, so moved her cage but I don’t think this has made a difference.
She’s not old so I don’t think that is the problem as she is only about 6 months old.
Could someone please tell me what I’m doing wrong or give me some advice as to what to do with them? My friend will probably want the boys back sometime this week!
Thanks

I would suggest you contact foreverhamsters for advice hana however I know he is away on hols this week. I don't think (though not certain) they stand as syrians do. I would keep trying them every night. Try at different time of day and evening and see if you get a mating. I think mating is quite quick as the male like to get it over with as quick as possible I beleive!!
