Swollen face, no discharge, normal behavior, help me please. 🥲

[HopeDelight]

My 4 year old Orpington hen and rooster both have a swollen face, one side is worse than the other on both of them, there’s no discharge, they’re acting normal, eating, drinking, everything. I thought that maybe it was a bug bite or sting, but since they both have it at the same time, I thought that’s probably not what it is. I remember that my other rooster had something similar a few years ago, he recovered but has labored breathing, although I’m not sure if that was to do with the swollen face.
I wormed my flock yesterday with ivermectin, which always works to worm them and has even sorted some illnesses out pretty quickly. I don’t know what else to do… it doesn’t look that serious, but I’m worried if it gets worse.

These are the only ones affected. I have more hens in the same flock. x I separated the sick hen last night, and I want to do the same with the rooster later on.
