Swollen chin and bruising help

[SplendidDogFeet]

Pecking order battles have begun (they're almost six weeks) and this kid is so beat up. Bruising on the face and a swollen pocket on the chin. I need to know if I need to be doing anything for treatment. I absolutely don't want to remove (I'm assuming it's a him?) unless absolutely necessary so that they don't have to keep starting over, but I also don't want some abscess rupturing because I was too stupid to know how to treat it. Not interested in losing any other birds. Kiddo is eating and drinking and active. Thank you so much for any advice.

That is a Guinea right?

Yes, but I figured that wound care is the same for most poultry.

I think it looks like the swelling under the chin is going down today? I'm hoping that's a good sign.
