My beardie who is approx. 2.5 years old, has some yellowing but it only seems to be between the scales on her head. None of the scales or spikes themselves are yellow. Im not sure if this is a start to fungus growth or regular color changes. Wondering if I should be worried.
The yellow between the scales looks normal to me. I'm not sure about the dark spot. It looks like there may be a head shed coming on and it may be related to that, but keep an eye on it.
