If it is the first time that she is pregnant it is usually one or two, but if after that it can be anywhere between 1 and 4
63-72 days
2 to 6 babies.
no because they are both female but they would fight if they wanted to make babies with a male.
No. There must be a male and a female for the guinea pigs to have offspring.
Most can if they are old enough
not particularly, there are many female and male guinea pigs
Not unless some form of artificial insemination is being used to impregnate them. Female guinea pigs cannot self-impregnate.
Yes, guinea pigs must mate to produce offspring.
yes
she sweeks and hoots
I would not recommend it. Just have the Mother Guinea Pig in with her babies separately. Sometimes the other guinea pigs can get excited and accidentally stomp the babies to death so best to keep Mom & babies separate.
usually guinea pigs have litters of 1-4 babies
