New owner i have some questions.

[Zobeyda]

So ive had my bearded dragon for a couple weeks and she has this thing on her mouth that looks like an injury but maybe im just paranoid. I see her everyday and constantly checking her but this looks new. Also her nostrils look like they have stuff in them? I'm wondering if there's something I can do for her.
Second question, she has shed that is still on her, she was shedding when I got her but she still has small pieces here and there on her scales, do I remove them or wait until they fall off on their own?
Third question. Her scales on her back and head turn green/black sometimes and then change back to normal but her beard stays the same. Is this a temperature issue or just something they do?
Final question. She doesn't eat much during the day, she might still be getting used to her environment but when I feed her she eats about 3 worms and 2 roaches and some greens but that's all she wants for the day and I don't think that's enough.
PS she is 5 months old, 13" long and currently in a 20 gal tank while I finish building her 4x2x2 tank to be done in the next few days. Currently She has a reptisun T5 HO 10.0 uvb and a 100watt basking bulb. The tank temp is 88 °f with a 103°f basking and a 78°f cool side. I feed her greens, dubia roaches, horn worms and superworms. I've been giving her baths for the shed about every other day and she's a very active girl.

She looks good -- her snout looks like shes been rubbing her nose on something like the glass maybe ? Please leave the shed alone - do not pick at it you could damage scales causing an infection- she looks like she has a stuffed up nose which would be shed - just leave it - it will come out eventually - the other parts of the shed let them do their thing- does she have stuff to rub up against ? Also when the shed gets to be crackly and dry you can take and mist her in the tank get a baby soft toothbrush and gently brush her the loose stuff will come off -- where is she sitting when her back turns color? The T 5 is strong for a 20 gallon tank - can you show me the screen please?

That's what was recommended to me and as I said in about 3 days she will be switching over to the 4x2x2 tank with a 34" uvb light. I had a T5 HO 5.0 uvb before this and I was told she needed a 10.0 since the light sits on top of a screen so I changed it. And I haven't noticed a pattern when she changes colors just every now and then it goes back and forth. I did notice though that it never turns black when she's soaking. I've attached a pic of her with the color change from yesterday. She will be in the same spot and be bright yellow/orange and then later have black scales.
Thanks about the shed! I had a leopard gecko for 9 years and I am used to them who shed in one go basically and it seems bearded dragons shed in patches so I thought maybe the shed was stuck. But ill definitely leave it alone, I do make sure when I soak her to get a little bit of water on the shed just to help a bit without messing with it.
