» Odd Behavior, Tanzi is STILL biting me

Tanzi is still really aggressive and mean. I can't even put my hand in the cage without getting mauld. Here babbies all of them are scared of me no matter what I do they swat at me with there paws, squeek, and run off. New girls become a total spaz, she's more active then ever and she nipps sometimes too. Tanzi's baby the one she is still with squeeks alot too, but it doesn't seem like they fight. What is going on with these hamsters?
Oh. ps sorry if this isn't under the right topic, but I though due to Tanzi's being pregnant when she got really nibbly.

Sadly many Dwarfs end up like Tanzi. You may have to accept she will never be tame and handle-able ever again. She may be hormonally off balance which there's nothing which can be done to balance her back,or it could still be diabetis and her blood sugar is causing her aggressions. As for her pups they are mimicing their mothers actions to you,BUT they may also have the same health issues as Tanzi

I myself would try separating the pups completely from Tanzi, and even if it means using a glove at first I would be sure to handle them(be sure your handling each one of them and not the same one over and over) as often as is possible each and every day so they can learn humans are not bad evil things. It is most likely an effect of Hybrid breeding from commercial farms which is causing the temperament issues and the odds are probably in favor that even though not bought at the store your rescued trio were from the same stock and why their past owners were ditching them to the wild if nobody came along to take them. So you have a huge hard thinking to do on how to enjoy a group of not so friendly dwarfs. You need to make them as happy as is possible until their called to the bridge. I'd make them a look but don't touch pet if they were mine. I'd also steer clear of any more Dwarfs from that store and not buy unless you can see the owners/breeders/seller stick their hand in the cage with the Hamsters sound asleep and still be able to pick them up bare handed with no sign of any aggressions. If they can't or won't do that then thank them for their time in showing them to you and walk away without. I'm so sad you got Dwarf Hamsters who ended up so aggressive. I do wish I was near enough to give you one of mine but as you said I'm too far a drive for your Parents to drive

I didn't want to admit it to myself, but is probibly the case. So my next question is I want to put them in bin cages and seperate them all what size bins are okay for one single hamster and three brothers?

I would use 58 liter bins since they will be in their bins till they pass on to the bridge. The next size down is OK if you can handle them and give them out of cage time in a ball or the bath tub etc each day. Let them have lots of fun toys to enjoy too. Also don't be hard on yourself that Tanzi and the pups didn't end up tame friendly pets. You still have gave each of your dwarfs a far better,happier life then they would have had without you taking them in.
