Our poor ducky Norie seems to have caught something, or had breathed in something that has made her not feel well. We just started using DE in their pen, so I wonder if the powder is upsetting her lungs. Her breathing sounded labored last night so we brought her in this morning. They wanted to put her in an O2 chamber to make it easier for her. She's also getting an x-ray and medicine. We had to put down a $500 deposit, but it could cost up to $1400 if she needs to stay in the chamber for more than 1 day (they said maybe up to 3). Hopefully it's not a fungal problem (we did find that some of their feed had gone moldy at the bottom on the container about two weeks ago, of course we threw it away immediately and bleached the storage container.) Ming Mei recently was at the vet because she lost her voice a bit, and we worried she might have been getting sick.... It seems whenever one duck gets sick, Norie has to go and get sicker. She's always been a bit of a runt, and she grew funny so she's kind of weird looking. She hates taking baths and will jump out of the tub every time. She hates the spray bottle/hose/kiddie pool too. Such a weird duck... Anyways, If anyone has an ideas or input or had problems with DE, tell me about it.... I'd like to be as informed as possible. We sprinkle our DE around their pen, sometimes while they are in it, so I'm feeling like that was the cause.... This was probably our own fault.
