What is the average weight of a 2 to 4 week old male guinea pig?

Question

I have two male GPs and one of them is about 2 weeks old, while the other is about 3-4 weeks old. The 2-week old is 220 grams while the 4-week old around 400 gms. Are they underweight?

Answer 1

no, they are not, thats a good weight. If you want them to get a little bigger, give them lots of hay, unlimited hay, 1 cup of pellets and 1 cup of veggies and 1/4 cup or fruits. Fruits are high is sugar so you do not want to gove your pigs to much fruit.
