Got home from work to find my year and a half old bearded dragon with a black beard. Took her out and it disappeared. Gave her a bath, she ate, she pooped, normal stuff. Put her back in her viv and about half hour later it was going darker again. But as soon as I stroke her head, she sees me or I get her out it disappears. She laid infertile eggs about 5 weeks ago if that is relevant. Her basking temp is around 37C and her cold side is around 30C. She has a Zoomed Reptisun 10.0 Lamp, 30 W, 36" 914 mm. Is she just being hormonal or maybe wants more attention? I can't seem to figure out why it's going darker. She's not aggressive in any way either. She does seem kinda thirsty but doesn't look dehydrated. Her urate was also orange so I probably should cool it with the calcium. Any ideas?
