I'm so sorry to hear it. I just went through a rough 'bout of MG myself. Had to put the whole flock down. I hope you can figure out what's going on with yours.
The bubbly stuff in the eyes concerns me. That's one of the same symptoms mine had. Another thing I noticed right away was that the sick ones quit being part of the flock. They'd stay in the coop, or be standing off in the corner of the run while all the others were piled up together. It was quite sad as I had come to learn that they are very flock oriented and like being together.
Will the dept. of ag not come to your house and pick the bird up? Mine did. Ask them if they'd come to you. The worst they can say is "no".
Oh, I don't think we've answered your egg question yet. You can eat the eggs as long as you haven't treated with antibiotics. If they're on antibiotics, or even medicated food, then you shouldn't eat the eggs. The danger, according to what I've read, is that you would be ingesting the antibiotics as well, and it's not a good idea to ingest antibiotics if you aren't sick or don't need them. It causes your body to react adversely if you ever do need antibiotics (like you'd build up an immunity or something and then they wouldn't work, or you might kill off beneficial bacterias normally present in your own body and then not be able to fight off an infection down the road.)
But as for eating the eggs of sick chickens, even after mine were deemed to have MG, the dept. of ag told me I could eat the eggs. The respiratory diseases that plague our chickens don't affect us humans. For a while I considered keeping mine as a "closed flock" and keeping the survivors of the MG, and I was planning to eat their eggs. Then I realized that every time they got stressed, they might break out with an active case of MG again, and I just didn't want to keep treating sick chickens for years, never being able to get any more.
I am going through something like this right now (treating with an avian vet ) with one of my Aracaunas. In our case it is a sinus infection.
Is the side of the face where the tear duct is bubbling swollen at all?
My Aracauna had the same symptoms as well as the white cheesy substance in the eye. The sinus cavity runs underneath the eye and the infection sort of weeps out of the eye. The infection starts out as that liquidy stuff and as it progresses it turns more egg-white like until it finally gets to that sort of cottage-cheese consistency.
If any of this is like what you are seeing then separate the sick bird. Apply wet washcloth compresses (warm, not hot) for about 15 minutes at a time 3x a day to the side of the face to help keep that liquid stuff moving out. It is turns into the cheesy stuff it gets all blocked up in their sinus cavity it can't be sucked out with a syringe.
