1 Wart like lesion on both wattles

[Crazy chickn lady]

I noticed that one of my little chicken children suddenly formed one wart-type lesion on both wattles, nearly exactly the ssame spot on each side. Her behaviour is normal and her appetite is the same. I live in Perth, Australia and we are currently going through a heatwave - been 40 degrees for nearly a week and night time temperatures are around 25-28 degrees.
Anyone know what it could be and how to treat it? Sorry the pictures aren't the best!

Hard to tell what that is. I think I'd monitor those 2 places and see if they get better/worse over the course of a few weeks.
