I have an 8 month old female pastel that weighs approximately 222g. Is this a normal weight or am I under feeding her? I've seen others that aren't much older than she is that weigh much more. I'm not sure if those owners are trying to beef up their females to breed sooner or if I'm just not feeding enough. She is an aggressive eater so that's not the problem. I just want to make sure her weight is on target. Thanks for your help.
