Yes you need to.
No, you should not touch them right away. Wait for a few days (a week or so) and let them get use to their cage and their parents. Then pick them up.
You should keep the baby guinea pigs with their mothers until they are around 3-5 weeks!
I'm Laura and I own 14 guinea pigs and no a baby guinea pig cant have no hair baby guinea pigs get born with hair and everything (very unlike baby bunnies) so they can run and eat straight away when they are born they practically look like mini adults
Baby guinea pigs will usually fit right into the palm of your hand, and have quite large feet; adult guinea pigs are easily the size of a football.
It will scare them but you can hold them. Also if away from the mom they will squeal loudly and they can be with the male and if you can hold a baby and the dad guinea pig together they will get along.
Well you see i dont think you should put the babies with the father at first their is a good chance that he mistakes it for a nice carrot but the mother will clean it and natures instinks will be their right away
Baby guinea pigs can be taken away when they are any younger then 4 weeks old. The topic is debatable but after 4 weeks should be fine. Especially if it is eating and drinking on it's own.
3 to 4 weeks old.
No, the male wont harm them.
I wish i could help but my baby guinea pig didn't like its mum after 3 weeks because she was sick and died. . . .
Yes,he should be separated from the mother as well as the babies because he can cause serious problems to the babies such as pregnant among baby Guinea Pigs,injuries,etc. When the babies are at two weeks old,you should distinguish between male and female baby Guinea Pigs and separate the male baby Guinea Pigs from the females.You can put the male babies with their father and the baby females with their mother.
baby guinea pigs will suckle mothers milk
