Please tell me this is just a sore and not something much worse??!!

My latest chicken experience has turned out to be a nightmare! I got 2 chocolate orps & 2 olandsk dwarfs for Christmas. These 4 birds came from a NPIP/AI clean breeder with a good reputation. less than 24 hours after I got them 1 of the chocolate's died of cocci (I am pretty sure as I saw blood and he was fluffed up, I couldn't get the corid in him in time) These birds have not touched my property but are being held in a building up the road to ensure the safety of our flock.
Side Notes: they had mice/lice and have been dusted for that all well.


I have another post asking about issues with another one of these guys but this little guy came to use with a pink swollen comb and I cleaned it Monday and put Neosporin (not pain relief kind) on it. This is what it looks like today. Is this a scab? It is hard to tell but does not seem crusty like a scab. Almost like the skin but I could be wrong. I cleaned again and re-applied Neosporin. Is there anything else I can do? When I cleaned it the first time it did appear that there was a small cut on his comb on the area that is swollen.

I have never seen fowl pox but with all the other issues these guys have I just had to post to make sure this was NOT fowl pox.
