I weighed them on April 13. The boy weighed 634g and he is 12 months, he had gained 30g in 5 weeks, which is about 6g a wk. He had also been confined due to an abscess that just would not heal, so he didn't get to run and play with my female as much. His activity level was down for about a good month. The girl weighed 599g and she is 14 months, she had gained 19g in 5 weeks, so about 4g a week.. They look okay, I just don't want them to get fat. Do they keep gaining or do they level off at some point? They must level off or at least the ones in the wild do since they forage for their food all the time unlike NR. Thanks for you thoughts.
