Puppies leave their mothers at 2 weeks old so assuming you mean on their own then yes the can.
Do not date your hamster, it is entirely too young.
You leave it alone for about 1 month and 2 weeks. (Thats what I did)
You don't breed hamster babies until there at least 1 year old
Your baby will be 1 month old one month after their birth date.
WOW! Your hamster lived over-age usually hamsters live 1-3 years! So maybe your hamster in hamster years is 100!!!!
If the 1 year old hamster is a syrian hamster DO NOT put another hamster with it. They are hamsters that NEED to be alone. If it is a dwarf, hamster, it might be ok. Dwarf hamsters like having each others company. However, if the 1 year old hamster is not use to other hamsters, it might not go over to well.
Take it to the vet.
Sure, why not!
Well, I only hold my Hamster Babies after they are a month old. If you want to make sure, wait until they grow body hair and have already opened their eyes. Then you can hold them. But it really depends on the mother. If the mother hamster is a first timer, she may panic when you hold her babies and might eat them, so if your Mommy Hamster is a first timer, better make sure and wait until they opened their eyes. But if your Mommy Hamster is already an experienced one, they may allow you to hold her babies, let's say, about 2 or 3 weeks old. But to be sure, just wait at a minimum of 1 month. Hope that helps. ;)
A hamster can be sold at 12 weeks old or above, it's usually good to sell them then they're young and not when they're about 1 year old.
You need to wait 1 month for each hamster(a boy + girl of a same breed) to mature, and then make them play a lot with each other. They automatically have a baby hamster after a while.
Your baby is both 4 weeks old and 1 month old.
