injured comb - 4wk old bird

[arosenzweig]

It looks like one of the bubbles on the developing comb of this silkie mix has burst.

We lack experience to know if this is a normal part of the developing process or if something else is going on. Maybe a small paper cut from her box? A peck from another 4 wk old chick? What does it look like to you? Should I put neosporin or vaseline on it or just let it be and monitor for now? Pictures below.

Thank you,

It looks like he just got it cut on something, or another chick pecked him. It should heal fine without any help.
