Hi Bkaye. Oh my, that does look Owie! Poor baby.
At first I thought that was on her outer eyelid but on pic #13 it is clearly on her dictating membrane.
Only advice I would add is to apply warm moist soaks to her eye as often as she will allow. I've had a lot of roosters with eye injuries due to them being well, roosters and they have all been pretty agreeable to allowing me to do this.
Hopefully the soaks will allow you to get the scabs softened and removed with a q'tip. Once removed you will be able to better access what is going on. If there is an infection there you will be able to gently express fluid or solid pus from the lump with the q'tip.
Your pictures are excellent BTW. Good job!
There is the possibility that it is a tumor/s of some sort also although the lumps do appear to be whitish yellow under the skin. Personally I wouldn't go messing around with home surgery around the eye even with my husband supervising the procedure. Tumors can be highly vascular and bleed like Billy Blue Blazes if you cut into them plus the eyelid is highly vascular all by itself. That close to the eye trying to control bleeding with styptic powder on a squirming unhappy bird is just to risky IMHO. You don't want to blind her.
You are doing the right thing using the antibiotic ointment on it. Do you have any oral antibiotics laying around? If you do and you are good at math you can look up the recommended dosage for humans and titrate it down for chicken use. It will take a surprisingly small amount to treat her using an oral agent, giving her a tiny dose daily along with a probiotic. Not any vets around me that will treat a chicken so I've learned to be competent with DIY treatments.
As for the possibility of an infection, when you get the scabbing off, if you can gently apply pressure with a q-tip at the bottom of the mass and roll the q-tip in and up, you may be able to get it out through the opening you have created by getting the scabbing off.. I have done this with cockerels with eye injuries and expressed an amazing amount of solid pus from their swollen eyelids. Surprisingly, they hold very still for me to do this and are visibly relieved with the pressure is off their eye.
You are doing an excellent job with this and time will tell what you are dealing with. The warm moist packs (warm not hot) will also, IF you are dealing with an infection, help bring it to a head for you to work with. Keep using the ointment as often as you can smear it on her. If she has an injury under the eye lid it will melt and get between lid and eye. It looks like to me that she has been scratching at it and abraded the skin with a claw.
Sure hope I've helped and she gets better.
Thanks for the tag,
