I guess I'll have to catch her then. I have to admit, she is a very good hider. I ounce spent several hours trying to find her with no luck. She is a lot better if a hider than some of my previous hens. I once found a hen nesting on one of our grass cutters...
So coccidia is the bacteria that lives in the intestines and coccidiosis is what people call when they get sick from coccidia?
Yaay! Glad you are gonna catch her -- ask for suggestions and there will be lots!
As for coccidia, not exactly. There are lots of different bacteria, some good, some bad. Some bacteria cause intestinal illnesses. Some beneficial bacteria help digest food. In peafowl specifically, and birds in general, there are a number of different illnesses -- different KINDS of illnesses -- that can result in what looks like an intestinal illness, not just bad bacteria.
Coccidia aren't actually bacteria at all. They are tiny, single-celled parasites -- protozoa -- which can ravage a bird's intestines. Coccidiosis can kill a peachick very quickly, sometimes within 24 hours of the owner noticing the chick is unwell. That's one reason to be very aware of subtle signs of illness in your birds.
As birds get older, they tend to develop some immunity to coccidia, but with stress or intestinal worms or who-knows-what the trigger, sometimes even adult birds can succumb. Coccidia can be treated with amprolium (often sold as Corid, among other trade names) in the bird's water, and can mostly (though not always) prevented in chicks by using an amprolium-treated chick starter.
Worm infestations -- parasites which attack the intestines or other organs, can make it easier for birds to get coccidiosis, or even blackhead, because the worms weaken the bird and damage the bird's internal organs.
BTW, have you wormed lately? It just occurred to me that your one year-old could also be suffering from worms if it is doing weird gasping things. (Look up "gape worms.") It seems more likely he is learning to honk to sound the alarm, but if you aren't worming regularly, you might want to consider it. Lots of info here on the peafowl forum about worming peas
