Baby Bearded Dragon sheds skin one month old

[Iamakel]

Hello there. In December 2016 I bought my two beardies from a girl that couldn't keep them anymore. In my city, one beardie is 122$ and I bought both of them + terarium with 50$. She wanted to sell them as she was a 9th grader and couldn't maintain school + "parenting" so I mostly got them to help her out and because I love animals. When she got them (from a bad breeder), she got them tailless mostly:

The breeder told her that they are sister and brother but after I got them I did some research and noticed that the girl (yellowish white) is a Pogona Minor and the boy is a regular Pogona Vitticeps (I don't know how they could be brothers to be honest):

the female I think is a Pogona Minor:

Whatever, the "fishy" thing I'm creating this topic is this. She kept them together for one year and half and so did I. They don't fight and the girl (even she's smaller) seems more dominant than the male. I tried to separate them but they seem sad one without other (not eating much, hardly active etc). She laid eggs 4 times in 2 years. I decided in February to keep them. I had 7 eggs in the homemade incubator and all of them made it. One died after getting out of the egg and one died because he had such a big eggsack. Now they are all good. I feed them vegetables in the morning (around 10-11am) and Cinerea in the evening (around 5pm). I have a little colony of Cinerea due to my 3 tarantulas and I feed the beardies with the babies from the roaches. I tried feed them 3 times a day but they won't eat that much.

Today I took them out in the sun light to feed them and also giving them a chance to bask under the sun light. The bigger one (which is huge compared to the others) seems like he's shredding his tail skin. HE IS ONE MONTH OLD! Is this normal? Are there any chances that beardies overeat? This one eats a lot compared to others and I decided to give him not so many roaches as he used to eat (just 4-5 now).

Take a look and please tell me that he's okay. The one with the "broken" tail doesn't hunt by himself so I have to give him food by hand (opening his mouth with the little roach's head and put the head inside his month so he starts chewing and eating). Is this normal? He's not blind. I checked. He's observing everything around him when I take him out!

Thank you for your time reading this big text!

They grow at different rates so it's not unusual to have some larger than other or growing more quickly. That will also lead to them having different appetites. They all look pretty good in the photo. One has that nipped tail which may be from being attacked by another. The shedding is quite normal and will occur pretty frequently as they grow as well.

No, that one was born like that, with the zigzag tail

Ah OK. Not an attack then. From what I've read, the hatchlings that are born like that can thrive just as well as the others.
