These little guys can be held for short periods as soon as they dry from birth. This is advised because the sooner they are held the sooner they are tamed for handling and training. Be careful not to drop them, they are newborn babies.
you can hold them at about 1 hour hold with my guinea pig babies i just hold them straight away but i would wait for abut 1 hour for the sow and her babies to bond
look under it or wait to see if it has babies
Probably just to be safe a week or two. Be careful touching the newborns because they are very delicate.
You should wait 24 hours after birth before cleaning the cage.
If you mean how can you hold it after it's born...: It depends on the mother really. When mine were born, the mother had no problem in letting me hold her babies, but they needed feeding so i couldn't hold them for long. If the mother starts getting worried when you try and pick one up, then i suggest you wait a while until she's fine with it. Sometimes you could have to wait for a couple of weeks.
8 weeks or two months
You should wait until the mother wont suckle them anymore. aka start eating normal food
During the first couple of weeks, you shouldn't hold them a lot as they will still be feeding, but you can. Just after the birth the mom might not allow you to touch her guinea pigs, so you should wait a little while. (I warn you, baby pups can weak REALLY loud when being taken from their mommy, it almost gave me a headache.)
No I would wait until they are at least one month old.
Rebreed her and wait 30 days.
you will have to wait 2 weeks before clening the cage or touching the babies
one to three days good luck with the breeding!
