GRAPHIC! Chick with severely swollen face

[HuskerHens18]

In my opinion, the images I will post below are graphic and disgusting. You've been warned.





In a previous thread, I've been having lots of chicken deaths and several isolated cases. Im currently waiting on necropsy results, but am still having chicken health issues.
This Lavender Orphington is almost 4 months old.
Don't know the gender, probably cockerel.
Symptoms were refusing to eat anything but a specific feed and nearly killed himself by starvation, he was free ranged too. (I changed from medicated start & Grow to non-medicated, he only wanted medicated) Currently, he is weak and very slow. Then, out of nowhere, his face swelled like a balloon on one side. He can't see out of that side now.
I have one Jersey Giant that's had a small bubble on his face since he was a few weeks old(he's about 2 years old now), I assumed it was a birth defect as it never does anything and feels hard like bone. Could it be contagious or unrelated?

Normal side.

This happened in 24 hours. He's the only chicken I have with a severely swelled face like this. I have not touched it yet because I'm a bit squeamish.
What is it and what do I do?

Feed is Purina Medicated Start and Grow.
He was recently treated for Eimeria(type of coccidia) with Sulfa in his water. Treatment finished last week.
He's been separated from his flock for 3 days.
It has rained a lot and it's very humid.

Oh crap forgot to add he was given Panacur dewormer instructed by a vet on Saturday. Will repeat next week. I forgot the type of parasite found in his fecal float.

I know you guys are all very busy, but does anyone have any idea what could be wrong?

Few questions that need answered to help identify the issue.

1) have you used this dewormer on this chicken before?
2) is the lump hard or soft?
3) does it move if you push on it?
4) did you go to a vet about it?

If it happened as fast as you said I’m guessing a sting or bite of some sort. Has the swelling subsided at all today?

No, this particular chicken has never been dewormed before.
The best description I can give you is it feels exactly like bubble wrap. If I press any harder it feels as if it would pop.
No it does not move around.
I'm trying to contact my vet, but he will not answer.

His eye leaks a small amount of clear liquid.

The swelling is about 10x worse today, his face was just mildly puffy last night. When I got up this morning it was like this.
A sting is always a possibility I suppose? Would it go away on its own or would I need to use a cream or something?

A friend of mine had a hen that got stung by a wasp (she watched/saw the wasp/hen interaction so there was no question what it was) and it looked very much like this. I'm not skilled enough to say that's what it is, but definitely looks similar if not the same.
