My production red just starting acting very strange. I received her about a week ago from a neighbor, so she's been seperated from the others. She's about three months old. A while ago I noticed her with her mouth open, moments later she threw up what looked like water. She's also scratching at her throat. I checked down her throat and noticed that it doesn't look like she has a tongue, but the passage looks clear. She's been on medicated starter feed and every now and then I give her a few mealworms. The clear liquid looked like water at first, but then she shook her head and it was almost gelatinous. It also smells. What could this be? Any help and advice is greatly appreciated!
