@MiaCarter I didn't know about Teflon till I bought birds, and boy was I not happy! How something that toxic is allowed to be manufactured blows my mind. I'm sure it has to affect us humans over time. So the birds will just eat the charcoal? Very cool. I keep some in my medicine cabinet for the family, but will look for the bird kind. In regards to the first male's legs, he WAS dragging them behind him. Is there a chance he might have fractured them one time when I was catching him to give him medicine. I tried to minimize the stress by catching him in the dark. And he was perching after I put him back, but maybe? The two cages are brand new from Petco. Just standard flight cages. I only use bottled water for the birds and my family. Not sure if you heard about the water disaster around here, a chemical leak into the river, (we made it on national news for all of 10 seconds), but I never trust the water in this state. I'll check out that list you sent.
@Smurf with the male that died, I "thought" I heard a clicking once. He definitely had trouble breathing, and his last chirp before he went silent sounded more like a croak. It's why I treated from ASM. I used the S76 from ladygouldian. The standard treatment is to add it to water, but I followed the "severe" symptom treatment of a drop to the neck. I've often wondered if I overdosed him.

@dan78 I hope the female is ok. She is still chipper and active, but of course any loose stool she has scares me. I've been adding extra poppy seed to her mix, taken away her greens, and am going to treat her along with the male when the Ronex arrives. Then maybe treat them both for ASM. I just hope the male makes it that long. For some reason, on Sunday the male made it off the floor of his cage to his swing and sang ALL DAY LONG. Now he is on the floor again and looks totally exhausted. I did move the male upstairs in a spare bedroom. Even in his emaciated state, he would occasionally try to sing back to the female in the other room. Poor little thing. I might have to give up having a canary in my kitchen. I hate that, as I spend most of my time, there. But the risks outweigh the benefits I'm afraid. The greens I buy are organic and then I soak them in my sink with vinegar and sometimes a few drops of GSE for around 10 minutes. Sound okay? This is how I normally clean the produce for my family.
Here's a question. So I can maybe presume the problem isn't the water, or the use of Teflon. The only other unnatural thing I use is those Cascade packets in the dishwasher. Though I'm not sure what could be used instead? Also, I just found a picture of the breeders card regarding the male. It looks as though he was the only survivor of 5 eggs. I'm not a breeder, but are those odds normal? He made an off-hand comment that if all his babies survived he wouldn't be able to sell them all. I understand that in nature only the strongest survive, but sheesh! Thanks again!
