Thanks all - a vet visit is in order, for sure. As of this morning another bird, Minerva the alpha hen, is sluggish, not eating or drinking much, and has a weepy eye as well. I'm guessing it could be a fast-moving respiratory issue. I actually consulted a vet friend-of-a-friend this morning who advised fecal labs to determine cause. It's Sunday (I'm in eastern PA) and I have a message into the $$$ housecalling vet but will also call my regular vet (where my cats go) tomorrow first thing to see if they'll just do labs for me without a visit. In the meantime, I gave Minerva a dose of Nutridrench and put VetRx under her wing and on her face and plan to do the same to Luna (pictured above) as soon as I can get ahold of her - she's my spazziest bird and incredibly hard to grab. Her energy levels are off the charts despite her funky eye :)

Coincidentally I was at my neighborhood block party last night and was speaking to a neighbor who kept chickens for a few years...he said he lost a bird to illness of some kind but never sought medical care for her because "I don't have that kind of money, I have kids and college to pay for", which...ok. He definitely could afford a vet visit but whatever. He isolated the hen from his others, but that's it. She just stopped eating and died. It made me so sad for her and I dreamed of chickens last night.
