Cracking sounds in jaw

My female beardie is about a year and a half. I adopted her a month ago. Didn't think I could love a beardie more than my male beardie, but omg she's the sweetest thing ever!!

She prefers to be hand fed, and I noticed that when she eats, everything is quite crunchy (like she is just a loud eater)... till yesterday when she was hanging out on the back of the couch, above my shoulder, when I heard this loud crackling noise, I looked over and she was yawning!! Umm... Is she ok?? Is this something I need to watch closely, or will she possibly grow out that? I rescued my male at about 2 years of age. So I never have had a young beardie.. She's not too much younger than he was when I got him, but I've also never had a female either.

She's very healthy! She was pregnant (all infertile eggs) when I adopted her. After she laid 34 eggs!!... she's still a chunky monkey! lol Its definitely not affecting her eating! I love her dearly already, can anyone tell me what that cracking noise is when she eats and yawns!?!

My guess is that it's just her joint cracking if she opens her jaw widely. As long as she is eating well and otherwise behaves normally I wouldn't worry about it. If it was bothering her then I would imagine it would affect her eating pretty quickly.

Ok, thank you!! I'm going to keep an "ear" out for it, made sure it doesn't get worse.. Just had to ask if maybe that's something other people have noticed! ?
