Large lump over chickens eye for several months now

[Netchicks]

My black copper marans has had a large lump over her eye for a while now(maybe 6 months or so). It doesn’t seem to bother her and she can still see. She is laying as well. I was concerned with lancing it since it hasn’t changed but I would love some advice.
Thank you

Has it become larger over the last 6 months? Does it feel hard or soft? It could be an ingrown feather cyst, but being so close to her eye and sinus cavity, I would be a bit nervous messing with it. If it is a feather cyst, there would be thick yellow material inside, along with a feather if you lanced it. If I did try to lance it, I would need someone to hold her wrapped in a towel like a burrito while I did the work. A vet might be safer. Or you could continue to watch it. There probably is some limit to her vision on that side.

Mine has a lump on her ear for the last 2 years. If it doesn't bother her, it's fine. My vet says it's either a benign tumor or a cyst, and that removing it might be worse than leaving it be due to the dangers of stress, surgery and anesthesia.

I tend to just watch things and treat conservatively. There is a case in the link below where a feather cyst eventually grew into the spinal cord causing paralysis. I thing that is an extreme case though. There are several examples of feather cysts in this article:

It has not changed size in over 6 months. I haven’t palpated it recently to see if it’s soft or hard. I will do that today. Thanks for the advice. I was worried about lancing it bc it’s so close to her eye and she doesn’t seemed bothered by it
