My beardie is 15 weeks old and she seems pretty happy. When shes in her viv shes relaxed and all her marks pretty much go. But when i take her out they come back and quite strong. Its weird though, because she is becoming quite tame and she comes out on her own sometimes and jumps on my hand and loves to explore or sit on my shoulder and doesn't seems stressed at all, yet the marks show? Will this go with age? Is it because she is still pretty young?
