she is drinking thankfully. I have her in isolation right now with a heat lamp on her at night. I also gave her some vitimins, garlic, and Ronidazole to help if she does possibly have canker and to help her from getting it if she doesnt. Im sure she is under a lot of stress. Ill have to get some vinegar and give that a shot. Gonna be ordering some Sulmet 12.5% (Sulfamethazine) from foys as well. Should be good to have on hand.
I would not treat with medication if you don't have a diagnosis, as the medications can complicate the sour crop or other crop issues.
I have also treated crop issues(very smelly breath, and crop with water) with Apple cider vinegar, probiotics and garlic caps. You have to be consistent and treat the bird daily, until all symptoms are gone. It works, but you have to be attentive to the bird, and keep a close eye out- as they can choke on any access fluid that comes up.
I gave my bird a soft gel garlic cap down the throat, then probiotics cap later in the day, and ACV water to drink, and did this each day until it was gone. The caps enable the birds to get a good dose, which they othwerwise may not get if they are allowed to drink as they please.
