Not poultry of course, but still a bird health emergency, so I figured this is the right place to post it. This morning, I found that one of my parakeets is acting strangely, and definitely looks sick. I have two parakeets, Blue and Pigeon. Blue was being her usual self, climbing around and playing. But Pigeon, who normally joins her in her activities or stays nearby and sings, was instead sitting on his perch quietly, all fluffed up. He sneezes every now and then, but nothing looks runny. He's a very shy bird and normally doesn't like me approaching him, but today when I came near the cage he just looked up at me tiredly. He's napping right now. Last night both birds were their usual cheerful selves, so it's quite sudden. They spend most of their time out of their cage, but I always keep an eye on them when they're out. The only thing I can think of that they did was they found the cat's water dish and took a bath yesterday. However Pigeon only lightly splashed his chest, while Blue had went and rolled in the water and got soaked, and yet she's fine. Anyway, what should I do for Pigeon? Should I separate the birds so Blue doesn't get sick? Any advice?
