Right after birth.
Male guinea pigs can succesfully imprenate a female guinea pig at (I believe)only 8 weeks of age, however it takes about 9 months for the guinea pig to be fully grown.
well i have 2 guinea pigs. their names are Sandie and Bob. At a very young age I fell In love with Guinea Pigs, they just facinated me. On the private part of the female, you will see a Y. On a male the letter would be an X.
Female guinea pigs sexually mature very early. They can actually begin to reproduce at 3 to 4 weeks of age. Pregnancy is especially hard on a guinea pig, but even more so at this age. It is usually recommended that you do not allow your guinea pig to breed, but if you are going to, wait until they are at least 7 months of age to allow them in with a male.
between 6 and 10 months for a female, not particularly important 4 male
yes, almost any male can get almost any female pregnant, in fact you cannot let a male in the same hutch as a female even just for half an hour, and a male can get a female pregnant again just after a half an hour if left in the hutch
Well, it really depends, see, if you are planning on getting two guinea pig's it's not the best idea to get two males.. They tend to fight. So if you are planning on getting two guinea pig's I suggest that you get either two females or a female and a male. But, if you get a male and a female , they can have baby's but females usually only have baby's after about 4months of age. But if you are planning on getting just one guinea pig, both males and females are great!
Male guinea pigs have been known to make a female pregnant when they are only a month old. But usually the male becomes fertile and wants to breed around 3-6 months of age. If you are planning on breeding, I suggest not to because the risk that the female will die giving birth or that she will give birth to "lethals" (babies without eyes or have crooked teeth) is high.
There is usually no problem with adding a new guinea pig even if you already have one. The best combination is to have a female, then introduce a new female. It isn't a good idea to introduce a new guinea pig if you have a male, unless you bring in a female because you want them to breed. If you must add a new male, try wshing it first to remove all old traces of its previous companions, as male guinea pigs are a lot more territorial than females.
No, guinea pigs need a male around in order to mate. What probably happened is your guinea pig was pregnant when you bought it. This is quite common since guinea pigs are hard to sex when they are young but can however, reproduce at a very young age.
Guinea pigs can reproduce as early as about 6-8 weeks old. You want to make sure that males and females are separated early to prevent unwanted pregnancy. You should not breed a female guinea pig over 6 months of age due to a high risk of complications.
You can tell if a guinea pig is a boy or girl at the age of 4weeks
The size of the groundhogs can help you tell their gender. The bigger one is usually the male while the female one is usually smaller.
